I get very tired of starting a video and they start begging for L&S in the first MINUTE. Many times, I immediately thumbs-down and post saying to cut that crap out. I also set the channel to "not recommend." I did this to a channel about guns and the guy actually cussed me out in the comments over it. I screen-captured it for proof.
Woah. I’m not a UA-camr, I’m just a guy with a channel. I also like to make content how I enjoy watching it, and I too don’t like the relentless begging. You all can think for yourself and do as you please, just as I do.

YES when you mentioned about the unsubscribing, I checked and had been unsubscribed. I have been listening to your videos for a long time and definitely didn't unsubscribe. But I subscribed back just now. Crazy. That is an interesting motor. I work on motors and generators in industry and for a hobby on antique stuff. That type of motor (in industry) is called a permanent-magnet synchronous motor, or an electronically-commutated / brushless DC motor. The part with the magnets rotates and is called a rotor. In any motor the rotating part is the "rotor" and the stationary part is the "stator." In the case of the Nissan motor, the rotor wouldn't really be considered an armature. That name implies it has "arms" or pole pieces with windings around them. With most alternating current motors, the stator is the armature. With a DC brushed motor like a starter or blower motor, the rotor is the armature. The brushes create alternating current on each individual coil of the rotor as it turns and the commutator segments related to each winding pass the brushes. In this motor, the stator receives alternating current form the drive electronics, and is technically the armature. This will likely get a lot of blowback from those not in the industry but if you look at the engineering definition you will see I am correct. It is interesting that they used sealed bearings in the motor. Those have a finite life; unlike the gearbox which has lubricating oil which can be renewed. That is a life-limiting point on this design. Another thing I am trying to understand is why you were afraid and concerned for your safety to take the motor apart. Is that some sort of "thing" in the auto motive EV world that they have been indoctrinating into people? I would never worry to tear apart an electric motor. If the power is off, it is not dangerous beyond the magnets in it. Thanks for making this video. Really enjoyed it! Also, again UA-cam unsubscribed me from you. That is frustrating.

Funnily enough, the newer leafs that make 200 hp effectively have the same drivetrain as seen here. The inverters have a higher power limit set, but the physical hardware is the same. People who have used leaf motors in conversions have tested this motor to over 250kw (335 Hp).

Appreciate you taking the time to pull one of these. Some people just love learning the insides of these for fun. Even if we don't plan to own or work on one, learning should be a life long love :)
I love that you spoil us with cars and motors that wont even make you money and that you do it for us and i thank you very kindly i don't care if its motor tear downs or flood revivals or personal projects i will come back and watch and like 👍
Reminds of the electric motor in an old school electric racetrack car. The motor in those were driven by two magnets on either side of a coil, Nissan has done the same thing just on a larger scale. Things your channel reveal is so fascinating, thank you so much Eric.
Very cool to see something different. You do have to love the simplicity of most EV drivetrains. I wonder how hard it would be to use just the motor side of this in a EV conversion of something like a Miata or older Geo Tracker. :) I like watching you tear these things down so I can see if it is something I might want to avoid as a shade tree mechanic. Yes the carnage is fun to see. However for me seeing the engineering of these things is the high point. Thank you for the Insight you give us into all these different engines and transmissions you tear down.
Replacing the engine with an electric motor is relatively easy, finding a place for the huge battery pack and wiring up all the electrical systems will be the hard part.
Mouting not so easy, old way for conversions was big DC motor and adapter plate for the gearbox, fairly low tech and off the shelf, have a look at EVTV motor verks channel for years of , Jack unfortunately passed now but years of info.
This was a great one. Thanks Eric! As a former RC racer, I've played with many brushless motors. Was cool to see this superaized version of what I used to play with all the time.
I found your channel because of the Victory motorcycle engine teardown. I work on car and bikes, but the bikes side of UA-cam is how I found your channel. Even if they don’t get as many views as your usual videos, I hope you keep doing occasional teardowns of different or unusual motors. I enjoy both and I think you can get a lot of new viewers with these. Love the content!
Thanks for doing this dude. The later version of those motors are actually really common for EV conversions (I have one in mine with a hopped up inverter for more power). It's really cool to see the reducer box torn down, only ever seen the slightly revised one and I can see now that it does look like they changed the casting slightly. One note about the motor, some people do like to use those in conversions but since you disassembled the resolver, anyone using it would have to figure out the new resolver offset when they put it back together. I learned the hard way that they can be extremely sensitive to slight variations, so much so that Nissan laser etched the value on every motor housing after assembly.
I think it's so cool that you're expanding onto other drivetrains, Eric! It's the way of the future, regardless if we want it or not. It's super cool to see what makes an EV tick! I own both a gas Mazda and an electric Fiat, and it's amazing to think about how they do the same thing, yet share almost nothing in common mechanically. This was the first time I've seen a true dissection of a motor! Great video!
What a fun teardown... I often wondered what the inside of an EV motor looked like. Thanks Eric and love your humor ("It's so dumb but it's fun"). Happy Thanksgiving to you and your family.
Speaking of giant magnets, we had a guy in the 80's who responded to a burglar alarm at a radiology center with Cat Scan machines. While searching the premises he entered the Cat Scan room and was quickly disarmed by the giant magnets that sucked his duty pistol out of his hand. We had a hell of a time getting it back and the gun was magnetized after that.
@@Lazerchicken69They are, however they're essentially left on all the time due to the complex (and possibly expensive) shutdown and restart procedure.
A quick safety note: Use care anytime you handle an armature with permanent magnets- the magnetic fields are so strong, the armature can "jump" towards steel topped tables or other iron and steel objects, crushing your fingers in the blink of an eye. We had a guy at the Honda shop we called "Stumpy", since he peeled off the tip of a finger between an IMA rotor and a steel table top.
I thought that was fascinating. It was interesting to see that the armature was a solid magnet while the windings were around it. So it is a brushless motor and therefore has no brushes to wear out or get covered with soot or anything that would need to be cleaned off periodically to keep it running at top efficiency. With the three wire connectors on the back, I get the impression that it must be a 3 phase AC motor too. So there must be electronics that converts the battery DC to AC and then sends out 3 phases to the motor windings. I think it would be interesting to reassemble it now and see if it could be set to running again. You know, just for fun. 😁
after watching this, I can see why people love using the leaf motors for EV projects. Small, punchy, and simple with a splined output shaft, very nice!
We were looking semi-seriously at a Nissan Leaf of about that vintage until our condo board wouldn’t let us install a charger for it. I remember being impressed by its acceleration.
Great teardown, and look into the super simple future-once they get batteries better sorted. First of only two EV’s I’ve driven was a Leaf and it was blast, and the Rivian is crazy.
Thanks Eric! As the owner of a 2015 Leaf local grocery getter I appreciate seeing the internals. I'm impressed with the engineering and build quality of the drivetrain. I'm now going to prioritize checking the service interval on the gear oil and coolant. Unfortunately, the weak link in the vehicle is the battery life. I'm still at 75% after ten years, but the clock is ticking and the options for replacement / overhaul diminish as the car gets older. 👍
What would the battery cost be right now if you had to replace and do you honestly feel its worth the difference vs an ICE vehicle? Granted its no fuel pumps, filters and engine oil to change so thats a savings in itself. Ive looked at a Volt and Prius since im not a hybrid fan unless they came out with one that was gas drivetrain in the rear and EV in front so it was two systems totally independent of each other then i may consider it, at least if one system failed hopefully the other could get you home lol
@@young11984 - probably 10K installed for a new 24kWh battery in a vehicle that's worth 8K. That's why used LEAFs are so cheap. It's worth it to me to drive it locally for $30 in electricity a month (I charge at home 240V 30A). My 4 banger Tacoma would cost me $300 in gas plus maintenance.
check out Dala the Great (Dala's EV Repair on youtube) out of Finland. He's done a ton with the leaf with hardware and software hacking including battery replacements and upgrades. I'd be pretty surprised if a battery replacement were $10k unless you're including labor or getting a brand new unit.
That's a weakness of most EVs AND hybrids. The aftermarket business of remanufacturing battery packs is still in its infancy, but there are aftermarket Prius packs out there. Then techs need to be trained to handle 200+V safely.
@@nmccw3245 thats why i was looking into some EVs, something to beat around town and short 200mile parts runs or visiting plus my dad could use it for Dr appts and such too. Prius seems to be the go to as i know quite a few with 300k miles trouble free miles and were bought new and a few Volts also about the same. If i can get one used for $8-10k, get 100-200k trouble free miles out of it before any issues i will send it to the scrapper and not even worry lol
Thank you so much for doing this! I've always wondered how electric car drive trains are built. I love this channel. You always take it to the next level and make it so interesting and fun! Have a wonderful Thanksgiving!
Thanks for everything. I own a 2017 leaf with 85k miles which I’m selling and just bought a 2021 with 15k miles for $15k. Wonderful to see the guts of the motor. Love your channel and all you do. Happy holidays
it would be a good idea to check/change the transmission oil in them. 🙂 also,the 12v battery is a common failure area. causes a lot of warning lights on the dash,and weird electrical problems. it can also wipe out the Bluetooth.
I love the variety you are doing every now and then. The CVTs and occasional electric or Hybrid is interesting. They may not add their own inspection ports but you did find some forbidden glitter and it is cool to see how simple mechanically these units are. I also loved the video of the rotted in half Ram truck, partly because I just think those trucks are junk. Have a good weekend
LOVE this content! I drive an EV and repair / teardown vids are (of course) much harder to come by. It’s a nice addition to your regular stuff! Cheers.
I loved the "Dr Strangelove moment" when blue got stuck on the magnet near the end of the video..surely people here remember that scene with Peter Sellers.........
Hi there. I am a retired design engineer. My speciality is diesel electric marine propulsion systems. I was really intrigued with this teardown. I have never seen the inside of an electric vehicle but have always suspected that the were a permanent magnet motor running off three phase AC. There is nothing difficult about that type of motor, small compact and efficient. thank you for satisfying my curiosity
I would have been worried about there being some capacitors somewhere that weren't discharged and Eric turning into Doc Brown and screaming GREAT SCOTT after getting zapped.
Thanks for all your dedication showing us every manner of inspection ports, surviving wrist pins, visits from uncle rodknee and more. I’m not an American but I wish you and your family a happy thanksgiving. See ya on the next vid!
This was great to see. I have a 2016 Leaf and it's really fun to drive. Throttle response and low-end torque is nuts. I've always wanted to see what was inside the drivetrain and you showed me! Thanks!! BTW, the biggest problem that the disassembled motor will have is getting thousands of tiny metal chips from wherever stuck all over the armature magnet. The clearance between the armature and stators is very tight and it's almost impossible to get all the debris off the magnet. Get a strong, clean plastic bag over the magnet ASAP. Good you run a clean shop.
Eric, this is probably one of the cooler teardowns you've done on your channel. As most of us older internal combustion guys are not used to EVs, this one is an insight to the future. I've driven a Nissan Leaf and was able to roast the tires, so it's not a bad car. Keep up the great work. Happy Thanksgiving too.
Love all the content..better than politics. Btw, took my truck for service last week and the guys had 70" screen on the wall. Guess what was playing on youtube? I Do Cars of course! Shop owner says it's on almost constantly.
Thanks! As a retired electrical engineer who did 20 years of racing ICE cars and is now an EV freak, I enjoyed seeing the guts of the original Leaf motor. If anyone is interested in seeing more EV teardowns, I would recommend the Munro Live UA-cam channel for more than you will ever want to know about EV vehicle designs.
In my experience working on Leaf's the electric motors never have issues. I have seen one inverter failure. The gear reduction oil needs to be changed, I recommend it at 60k km. I have seen a couple gear reduction bearing failures, catastrophic bearing failures. Overall the leaf is a pretty reliable vehicle and I enjoy how they drive.
No oil filter on the gear reduction? I notice Tesla has an oil filter presumably to catch the debris at run in. I would say the metal in that oil has been there since 1000 miles
@@paulsimpson8990 there is no oil filter. I would also guess that most of the debris is from initial break in. Most leaf reduction gears I service have never had the oil changed and the oil is usually in terrible condition. I usually see them around 80-120k km.
@ it is a bit strange that the oil is that bad imo. I checked the diff oil in my bmw 335 after 12 years and 120k and it was as clear and clean as the day it went in. No lsd clutches to contaminate the oil.
New follower here, sent by Rainman Ray! That was a great teardown! I’ll have to go to your earlier videos to see what you’ve done so far! Happy Thanksgiving to all who celebrate!
No, I was going to ask if the water pump was reusable. 'This is the current situation (while looking at the coil windings)...' Slipped that one right in there. Lol. Regarding EV's. Diesel locomotives use the diesel engine to drive an alternator. The alternator supplies electric current to either DC or AC traction motors located in the wheel sets. Those electric traction motors drive the train. If electric motors can supply enough power to pull a mile long train consist, they certainly can push a car down the road. Of course, batteries are a different issue, but power-wise, electric motors get the job done.
And street cars since the 1880s used -- an electric motor! Those things were cast iron frames and weighed, er, just a bit. Electric locomotives without messing about with an intermediate diesel came along in the early 19 ought-oughts. Diesel electric was only "invented" where rail companies thought it would be too expensive to run extensive / expensive power take-off lines along the track. So not sure what you're trying to say here. Of course electric motors have enough power to pull a mile long train. The limiting factor is the puny output of the diesel engine, meaning many locomotives required to pull that mile-long train. I think you have things backwards.
@0:40 Well thank you Eric. But hey, we're just as grateful that you're taking the time to produce these very entertaining videos that you put out each week, and I thank you for that.
This EV teardown was interesting! How about donating it to a school that has an automotive class? Stuff the new mechanics are going to eventually have to deal with. Great show!!
16mm = 5/8" Found this out working on a Grand Caravan. Tamper proof when you can get the bits from the local parts store, etc. Funny when you pried that plate away at 6:10 I was ready for the oil to pour out. 🤣
Just think: Someone will be watching this video holding a notepad 10 years from now, trying to get an old Leaf running again. EDIT: Next week, we get to see Eric tear down an MRI. For what it's worth, that motor is probably fine. It would be amazing to electrify my Samurai.

I love that you spoil us with cars and motors that wont even make you money and that you do it for us and i thank you very kindly i don't care if its motor tear downs or flood revivals or personal projects i will come back and watch and like 👍
Reminds of the electric motor in an old school electric racetrack car. The motor in those were driven by two magnets on either side of a coil, Nissan has done the same thing just on a larger scale. Things your channel reveal is so fascinating, thank you so much Eric.
Very cool to see something different. You do have to love the simplicity of most EV drivetrains. I wonder how hard it would be to use just the motor side of this in a EV conversion of something like a Miata or older Geo Tracker. :) I like watching you tear these things down so I can see if it is something I might want to avoid as a shade tree mechanic. Yes the carnage is fun to see. However for me seeing the engineering of these things is the high point. Thank you for the Insight you give us into all these different engines and transmissions you tear down.
Would love to see a moderately powerful EV drivetrain dropped in a 90's Geo Metro. Lol
Replacing the engine with an electric motor is relatively easy, finding a place for the huge battery pack and wiring up all the electrical systems will be the hard part.
Mouting not so easy, old way for conversions was big DC motor and adapter plate for the gearbox, fairly low tech and off the shelf, have a look at EVTV motor verks channel for years of , Jack unfortunately passed now but years of info.
yes people use the leaf motor without the geartrain connecting it to diffs of other cars. But the geartrain is part of the advantage of the setup.
This was a great one. Thanks Eric! As a former RC racer, I've played with many brushless motors. Was cool to see this superaized version of what I used to play with all the time.
Great tear down, more please. I like seeing both propulsion systems examined. This helps demystify the EV vehicle.
I found your channel because of the Victory motorcycle engine teardown. I work on car and bikes, but the bikes side of UA-cam is how I found your channel. Even if they don’t get as many views as your usual videos, I hope you keep doing occasional teardowns of different or unusual motors. I enjoy both and I think you can get a lot of new viewers with these. Love the content!
Thanks for doing this dude. The later version of those motors are actually really common for EV conversions (I have one in mine with a hopped up inverter for more power). It's really cool to see the reducer box torn down, only ever seen the slightly revised one and I can see now that it does look like they changed the casting slightly.
One note about the motor, some people do like to use those in conversions but since you disassembled the resolver, anyone using it would have to figure out the new resolver offset when they put it back together. I learned the hard way that they can be extremely sensitive to slight variations, so much so that Nissan laser etched the value on every motor housing after assembly.
I think it's so cool that you're expanding onto other drivetrains, Eric! It's the way of the future, regardless if we want it or not. It's super cool to see what makes an EV tick! I own both a gas Mazda and an electric Fiat, and it's amazing to think about how they do the same thing, yet share almost nothing in common mechanically. This was the first time I've seen a true dissection of a motor! Great video!
Nope, electric is unsustainable.
What a fun teardown... I often wondered what the inside of an EV motor looked like. Thanks Eric and love your humor ("It's so dumb but it's fun"). Happy Thanksgiving to you and your family.
Speaking of giant magnets, we had a guy in the 80's who responded to a burglar alarm at a radiology center with Cat Scan machines. While searching the premises he entered the Cat Scan room and was quickly disarmed by the giant magnets that sucked his duty pistol out of his hand. We had a hell of a time getting it back and the gun was magnetized after that.
I always thought they were electromagnetic devices
CT scans are X-rays, MRI's are the giant magnets. So had to be an MRI that disarmed him which if true is hilarious.
@@zwhitehead403 MRI it was then and it happened.
Sometimes they have to turn the machine off. Costs thousands to turn back on.
@@Lazerchicken69They are, however they're essentially left on all the time due to the complex (and possibly expensive) shutdown and restart procedure.
A quick safety note: Use care anytime you handle an armature with permanent magnets- the magnetic fields are so strong, the armature can "jump" towards steel topped tables or other iron and steel objects, crushing your fingers in the blink of an eye.
We had a guy at the Honda shop we called "Stumpy", since he peeled off the tip of a finger between an IMA rotor and a steel table top.
Wot he said. Also I've seen the magnets crash together and shatter, throwing tiny ultra sharp shards everywhere.
@@ColinSBC there are absolutely permanent magnets in some 3p ac motors
I will always remember this, thank you for the warning.
Stumpy 😭
Yep those IMA motors don’t mess around.
I usually shim the IMA motor with cardboard from a cereal box in lieu of the special tool.
As someone who just bought a 2012 leaf, this is fascinating, another great video brother!
Electric Blue, that would make such a cool 80's song...
Ha ha see what you did there Mr Icehouse
I saw this comment and that's been stuck in my head for the entire video.
Song by Blue Oyster Cult. Then sing Godzilla for being a Japanese car.
ua-cam.com/video/_pqvjfW9yHo/v-deo.htmlsi=sT1qB6Rw0pytNrfK
Hmmm... There was an electric banana in the song Mello Yellow!
This is the “current” situation. Very subtle, I like it.
That would be a great magnet to put on your refrigerator door.
It would certainly steamroll anything in its way.
He should use it to extract bearing material out of blown engine sumps and filters
At least you can go magnet fishing now Eric 👍
I've been subscribed to you for a while, love it!
I thought that was fascinating. It was interesting to see that the armature was a solid magnet while the windings were around it. So it is a brushless motor and therefore has no brushes to wear out or get covered with soot or anything that would need to be cleaned off periodically to keep it running at top efficiency. With the three wire connectors on the back, I get the impression that it must be a 3 phase AC motor too. So there must be electronics that converts the battery DC to AC and then sends out 3 phases to the motor windings. I think it would be interesting to reassemble it now and see if it could be set to running again. You know, just for fun. 😁
Omg. I have been waiting for this day. So cool. Thank you and Happy Thanksgiving.
after watching this, I can see why people love using the leaf motors for EV projects. Small, punchy, and simple with a splined output shaft, very nice!
Whenever Blue got stuck to the armature it cracked me up.
I like your content I've been watching you for about 2 to 3 years now I enjoy everything you do
Been watching eric for many years. Love his channel.
We were looking semi-seriously at a Nissan Leaf of about that vintage until our condo board wouldn’t let us install a charger for it. I remember being impressed by its acceleration.
I'm thankful for you posting these teardowns. 👍
Great teardown, and look into the super simple future-once they get batteries better sorted. First of only two EV’s I’ve driven was a Leaf and it was blast, and the Rivian is crazy.
Thanks Eric! As the owner of a 2015 Leaf local grocery getter I appreciate seeing the internals. I'm impressed with the engineering and build quality of the drivetrain. I'm now going to prioritize checking the service interval on the gear oil and coolant. Unfortunately, the weak link in the vehicle is the battery life. I'm still at 75% after ten years, but the clock is ticking and the options for replacement / overhaul diminish as the car gets older. 👍
What would the battery cost be right now if you had to replace and do you honestly feel its worth the difference vs an ICE vehicle? Granted its no fuel pumps, filters and engine oil to change so thats a savings in itself. Ive looked at a Volt and Prius since im not a hybrid fan unless they came out with one that was gas drivetrain in the rear and EV in front so it was two systems totally independent of each other then i may consider it, at least if one system failed hopefully the other could get you home lol
@@young11984 - probably 10K installed for a new 24kWh battery in a vehicle that's worth 8K. That's why used LEAFs are so cheap.
It's worth it to me to drive it locally for $30 in electricity a month (I charge at home 240V 30A). My 4 banger Tacoma would cost me $300 in gas plus maintenance.
check out Dala the Great (Dala's EV Repair on youtube) out of Finland. He's done a ton with the leaf with hardware and software hacking including battery replacements and upgrades. I'd be pretty surprised if a battery replacement were $10k unless you're including labor or getting a brand new unit.
That's a weakness of most EVs AND hybrids. The aftermarket business of remanufacturing battery packs is still in its infancy, but there are aftermarket Prius packs out there. Then techs need to be trained to handle 200+V safely.
@@nmccw3245 thats why i was looking into some EVs, something to beat around town and short 200mile parts runs or visiting plus my dad could use it for Dr appts and such too. Prius seems to be the go to as i know quite a few with 300k miles trouble free miles and were bought new and a few Volts also about the same. If i can get one used for $8-10k, get 100-200k trouble free miles out of it before any issues i will send it to the scrapper and not even worry lol
Thank you so much for doing this! I've always wondered how electric car drive trains are built. I love this channel. You always take it to the next level and make it so interesting and fun! Have a wonderful Thanksgiving!
"But I'm actually trying to change what *normal* looks like." He said, standing in front of a Solstice. lol
Keep doing what you're doing bro. We love all the content on this channel because the best part is in every video and it's you! Cheers from Sweden 🙌
Thanks for everything. I own a 2017 leaf with 85k miles which I’m selling and just bought a 2021 with 15k miles for $15k.
Wonderful to see the guts of the motor.
Love your channel and all you do. Happy holidays
it would be a good idea to check/change the transmission oil in them. 🙂 also,the 12v battery is a common failure area. causes a lot of warning lights on the dash,and weird electrical problems. it can also wipe out the Bluetooth.
I love the variety you are doing every now and then. The CVTs and occasional electric or Hybrid is interesting. They may not add their own inspection ports but you did find some forbidden glitter and it is cool to see how simple mechanically these units are. I also loved the video of the rotted in half Ram truck, partly because I just think those trucks are junk. Have a good weekend
LOVE this content! I drive an EV and repair / teardown vids are (of course) much harder to come by. It’s a nice addition to your regular stuff! Cheers.
I loved the "Dr Strangelove moment" when blue got stuck on the magnet near the end of the video..surely people here remember that scene with Peter Sellers.........
I loved this teardown at least as much as the regular ones.
Hi there. I am a retired design engineer. My speciality is diesel electric marine propulsion systems. I was really intrigued with this teardown. I have never seen the inside of an electric vehicle but have always suspected that the were a permanent magnet motor running off three phase AC. There is nothing difficult about that type of motor, small compact and efficient. thank you for satisfying my curiosity
I would have been worried about there being some capacitors somewhere that weren't discharged and Eric turning into Doc Brown and screaming GREAT SCOTT after getting zapped.
Any capacitors would be in the electronics box.
That ending was pure comedy 😂 always looking forward for the this type of humor, one of the many reasons why I love this channel
LOL, Blue continuously getting stuck to the armature is comedy gold...
Thanks for all your dedication showing us every manner of inspection ports, surviving wrist pins, visits from uncle rodknee and more. I’m not an American but I wish you and your family a happy thanksgiving. See ya on the next vid!
Thanks. We own a 2016 Leaf. It’s been a great entry to EVs. Now have Tesla also.
Same story here. Our used Leaf is a great commuter car and convinced us to buy a Model Y as well.
Glad you mentioned it. I noticed that I was unsubscribed as well. Re-did it. Something is jacked up with UA-cam.
This was great to see. I have a 2016 Leaf and it's really fun to drive. Throttle response and low-end torque is nuts. I've always wanted to see what was inside the drivetrain and you showed me! Thanks!! BTW, the biggest problem that the disassembled motor will have is getting thousands of tiny metal chips from wherever stuck all over the armature magnet. The clearance between the armature and stators is very tight and it's almost impossible to get all the debris off the magnet. Get a strong, clean plastic bag over the magnet ASAP. Good you run a clean shop.
that magnet already had crud on it before the video was over. blue, the jacks and the table proudly sabotaging the EV
Eric, this is probably one of the cooler teardowns you've done on your channel. As most of us older internal combustion guys are not used to EVs, this one is an insight to the future. I've driven a Nissan Leaf and was able to roast the tires, so it's not a bad car. Keep up the great work. Happy Thanksgiving too.
Love all the content..better than politics. Btw, took my truck for service last week and the guys had 70" screen on the wall. Guess what was playing on youtube? I Do Cars of course! Shop owner says it's on almost constantly.
It's good to see out of the ordinary today as it could be what we are playing with tomorrow
Interesting. Happy Thanksgiving. Thank You from La Pine Oregon
Just so you know I find your presentations far above most things on UA-cam. Bravo, and keep up the good work!!!
🙂👌
You should do a Toyota hybrid e-cvt. Those things are wizardry
I've seen several second gen prius's go for $500 for the whole car.
speedkar99 just did a series on a gen 3 prius drivetrain that's pretty in-depth
@ I just watched that yesterday. Great video. Whoever thought that thing up is a genius.
This is like my dream job. Taking stuff apart and NOT having to put it back together myself. :)
Happy Thanksgiving wishes Eric.
Happy thanksgiving!
Really interesting tear down, the magnet stealing old blue stole the show!
All the best from Scotland 🏴
Interesting!!
As always!!!
I always learn from your videos.
This was cool to see :) Thank you for doing something different. Love all that you do
This was just fun to see.
you are having entirely too much fun there Eric, i love watching you do your teardowns
Thanks! As a retired electrical engineer who did 20 years of racing ICE cars and is now an EV freak, I enjoyed seeing the guts of the original Leaf motor. If anyone is interested in seeing more EV teardowns, I would recommend the Munro Live UA-cam channel for more than you will ever want to know about EV vehicle designs.
Totally loved the blue-per at the end of the video. Keep up the good work, and know - you have supporters somewhere in Bulgaria too.
Cheers, Eric!
So no malice in the combustion palace? 👉👈
Just wait! There’s a Saturday in the future
Which begs the question...is the "Juice" worth the "Squeeze"?
I mean it's possible for this to become a combustion palace but it might not be a palace
@@patturnbow8761
It was blue...
Did you see it?🤔
BLUE even got carried away with excitement.😂
@OperatorIHC No combustion so no palace.
These motors somewhat on my radar for a future project, so thanks for doing this.
In my experience working on Leaf's the electric motors never have issues. I have seen one inverter failure. The gear reduction oil needs to be changed, I recommend it at 60k km.
I have seen a couple gear reduction bearing failures, catastrophic bearing failures.
Overall the leaf is a pretty reliable vehicle and I enjoy how they drive.
No oil filter on the gear reduction? I notice Tesla has an oil filter presumably to catch the debris at run in. I would say the metal in that oil has been there since 1000 miles
@@paulsimpson8990 there is no oil filter. I would also guess that most of the debris is from initial break in. Most leaf reduction gears I service have never had the oil changed and the oil is usually in terrible condition. I usually see them around 80-120k km.
@ it is a bit strange that the oil is that bad imo. I checked the diff oil in my bmw 335 after 12 years and 120k and it was as clear and clean as the day it went in. No lsd clutches to contaminate the oil.
New follower here, sent by Rainman Ray! That was a great teardown!
I’ll have to go to your earlier videos to see what you’ve done so far!
Happy Thanksgiving to all who celebrate!
Thank god. No oil dipstick to remove. But on the flipside, no cram craps to cam loose.
Legendary
I always wanted one of those Solstices. Such a great look.
This is very neat! Thankyou!
You've got to have the best collection of automotive bolts ever.
No, I was going to ask if the water pump was reusable.
'This is the current situation (while looking at the coil windings)...' Slipped that one right in there. Lol.
Regarding EV's. Diesel locomotives use the diesel engine to drive an alternator. The alternator supplies electric current to either DC or AC traction motors located in the wheel sets. Those electric traction motors drive the train. If electric motors can supply enough power to pull a mile long train consist, they certainly can push a car down the road. Of course, batteries are a different issue, but power-wise, electric motors get the job done.
And street cars since the 1880s used -- an electric motor! Those things were cast iron frames and weighed, er, just a bit. Electric locomotives without messing about with an intermediate diesel came along in the early 19 ought-oughts. Diesel electric was only "invented" where rail companies thought it would be too expensive to run extensive / expensive power take-off lines along the track.
So not sure what you're trying to say here. Of course electric motors have enough power to pull a mile long train. The limiting factor is the puny output of the diesel engine, meaning many locomotives required to pull that mile-long train. I think you have things backwards.
@0:40 Well thank you Eric.
But hey, we're just as grateful that you're taking the time to produce these very entertaining videos that you put out each week, and I thank you for that.
Motor I'd love to see: A high mileage Volvo 240 4 banger. The flying brick motors always seemed indestructible.
This EV teardown was interesting! How about donating it to a school that has an automotive class? Stuff the new mechanics are going to eventually have to deal with. Great show!!
Thanks for making this possible, it means a lot to me and I drive a 2015 version and I love it.
2015 Leaf here too. If you change the reduction gear oil for something more synthetic, you can gain 0.5 mi/kWH in efficiency. I used Amsoil.
Thank you for sharing this "maintenance-free" motor video! Looking forward to hearing about those big projects, too...
Exercise in futility is the only exercise I get.
16mm = 5/8" Found this out working on a Grand Caravan. Tamper proof when you can get the bits from the local parts store, etc. Funny when you pried that plate away at 6:10 I was ready for the oil to pour out. 🤣
Just think: Someone will be watching this video holding a notepad 10 years from now, trying to get an old Leaf running again.
EDIT: Next week, we get to see Eric tear down an MRI. For what it's worth, that motor is probably fine. It would be amazing to electrify my Samurai.
been subscribed and watching for a long time now! Saturday teardowns have become a part of my weekly routine. I too am a lover of niche cars and you always provide top tier content whether that be the teardowns or you just working on your own projects! Im here for all of it. and ill continue to watch your videos as long as you upload them! ✊
The amount of bots that were here within the first few seconds was insane
I can’t even keep up deleting them!!
This was a cool change of pace. Love it. Thanks for doing this, happy thanksgiving!
