what do you think of this? I've done some calculations on a project of mine, but i don't know what is the lifespan of the motors. Turns out that if i use a DC motor (1-1 motor spin to tire spin ratio), i would have to run the motor no more than 850 RPM for my country's speed limit. what do you think about that range of RPM? in terms of motor lifespan and wear (considering that DC motors red-line at almost 5000 RPM if i am right ?) The only things stopping me are the transmission maintenance (would want to get rid of it if i could) , and motor overheating knowing that i live in a region of hot climate. Thank you :)
@@aslt5711 There's no reason to try to spin a motor that slow. The motor will have do draw a tremendous amount of current for the current you would need. The typical way to do it is to connect the electric motor to gear reduction, such as the existing transmission. This allows the motor to spin at thousands of RPMs. It reduces current draw and heat, and increases torque. All commercially-built electric cars use some sort of gear reduction. Even "direct-drive" EVs really have the motor go to the drive-shaft, and there is still some gear-reduction in the differential. The only exception are hub motors. They are a very different style design than a typical motor. No current commercially-built electric car uses those.
Try retrofitting with a D series Honda transmission. Many, many gear ratios to mix and match, many final drive gears... cheap... strong transaxle units.
Great video. I appreciate your attention to detail. I have been dreaming to convert my own vehicle someday to electric. I am an avionics technician so I can get my head around the electrification part. My trouble is the mechanical component of the conversion. The biggest thing is both of my cars are automatic. Obviously a manual car is ideal for EV conversion, and this appears to be all I can find on the interwebs is manual transmission conversions. Is it even possible or worth converting an automatic vehicle to ev?
The older models were great. Everything was analog and didn't have any electronics involved, except for the solenoid locking the torque converter to create a "fourth" gear. The newer models are totally controlled by a microprocessor. I don' t think you can get away with doing this anymore. :( ..And if you have a CVT transmission, I don't think it will put up with a high torque electric motor at all. It will probably break in a month. Constant Velocity Transmissions were designed for high gas mileage, not for high performance. Then again, if you have a manual transmission??
@@Yodaandhislightsabre there's a lot of different types of motors some old styles of dc motors are getting used as brushless. Sorry but i don't remember what they are called, be better at manipulating magnetic fields is opening new ways of making motors stronger and more efficient.
Great video and explaining , i would of kept the clutch plate springs to help dampening and ease the power transfer to the gearbox . Im abot to start a project thanks for the info .
U used a thinner oil to save energy? Electric motor is smooth hence no protection for hi-torque pulses is required. Go w thin ATF. Syncromesh might be a little affected.
You are better off using this original transmission as it has always been used because starting off in fourth or fifth gear places tremendous forces on the gears and they are likely to eventually break. And why not keep the clutch as well, just in case?

Due to the massive torque range of an electric motor you don't need to change gears. Most builders usually stick with driving in either 3rd or 4th gear. You can pull away with most self builds in 3rd gear.
@@TimpBizkit The amount of torque in an electric motor is so huge you don't need gears. Also, that torque comes from zero rpm and up. That's why electric cars have such massive acceleration. Even my ZS has acceleration in the region of 0 to 60 in around 7 seconds (TBH it feels a lot faster). Especially when you're leaving more renowned cars in your wake. The reason why a lot of electric cars aren't rated for towing is that a lot of manufacturers don't want to tell you how much the range is effected!!. The petrol version of the ZS is rated for towing. I can buy a towbar for mine, but it would not be legal to tow as mine is not rated for it. Towing would drop my range from around 150 miles to around 80 to 90.

Marc Brassé Your in gear 1, then power cut to the motor, motor spins free now (like a flywheel), then shift to next gear, power motor back on. So to mimick a combustion car: keep the clutch pedal in the car and connect to a motor on/off switch.
@@robertcaron9181 Still he talks about a gear box. This suggests you go through gears, which suggests you go through mutiple gears while driving. This suggets that the gearbox runs connected to the electric motor. How to do this smoothly is not explained. The only solution will then be to leave the car in one gear.
There are many cars which were available with a manual OR automatic. You can get a manual from a salvage yard and drop it in there. Alternatively, you could use a motor AND GEARBOX from something like a salvaged Nissan Leaf. You would then just need to make custom shafts from the gearbox/differential to the front wheels.
Keep in mind that it's no simple task to "just put a motor on....". A motor needs to be properly supported, exactly positioned, and be kept in place. That means scratch designing/fabricating/installing some custom motor mounts and brackets. The existing transmission is MUCH easier to use as a simple place to bolt the motor. I'm not saying it can't be done, but I'm struggling to think of any DIY twin motor setups done in that way. The Tropica was a twin motor rear-wheel drive vehicle with one motor on each of the rear suspensions, belted or chained to the rear wheels. Essentially twin motorcycle drivelines. Of course, there were only about a dozen of those built!

Then, you "Just" remove the existing motor and "Just" replace it with two separate ones, to eliminate the differential and the two driveshafts from it. It's "Only" one more motor, and you "Only" have to figure out how to do it, and "Only" have to find, buy, and implement "Only" one more Tesla motor controller, and "Just" design and build "Only" one more complete structural mounting system and "Only" one more complete driveline for everything to work.

So you only need the gear box if your car is a 4x4 or AWD or front wheel drive , or only to transport the movment , and no need to shift the speed by gear box ,,, but can we adjust the gear box shifting on the fastest speed permanently , and shifting the motor speed by the electronic buttons ?
I think it's great if you're seeking a single motor, but aren't most electric cars dual motors (one for each wheel) eliminates the weight of a transmission and a more efficient motor/generator...
No. Most electric cars use one motor to drive two wheels, using a traditional differential system. In place of the transmission is a single-speed gear reduction. The four-wheel drive Teslas use two motors, but it's one for each axle.
This applies to manual gearbox. Any tips on automatic ones? Or should I ditch the auto gearbox ? Any info would be great as I want to convert my Golf to electric power
Automatic transmissions are designed for gas engines, not electric motors. Typically, folks use MANUAL transmissions for EV conversions. An automatic is more complicated and less efficient. If an automatic is used, it's typically just locked in a single gear.

Nabre Labre That’s the concept of a plug-in Hybrid, such as a Chevy Volt. I did run this car for a while as a hybrid with a generator. Search this channel for “DIY plug-in Hybrid” for what I did.
@@BenjaminNelsonX what I am trying to do is not have to plug it in, just have a small battery bank to fill the gaps, and a generator for road trips/not getting stranded. I have another question, a motor I looked at on craigslist does 1800 rpm. In the car I'd be using, 6th gear at 3000 rpm is 60mph, so would i only get 36 mph out of that motor without overvolting? Thanks!
Nabre Labre does the motor say which voltage it runs 1800 RPM? That speed is very common for an AC motor that runs from wall power. Make sure the motor you want to use is DC. If it is, increasing the voltage will proportionally increase the speed.
You'd never want an automatic transmission for an electric car conversion. Most of the time, you'd be driving an electric version around in only one gear anyway. The automatic would be more expensive, less efficient, and mostly would just get in the way. Electric motors behave like transmissions with an infinite number of gears. They produce their maximum torque from zero RPM and can be driven around normally without shifting gears.
Devil's Offspring I'm in a project to transform an automatic gasoline car into an electric car. We are trying to figure out how to connect the transmition to an electric motor
@@beFrah, One way of doing it is to remove the automatic transmission, and putting in a manual transmission that would have matched that car. You would then do a clutches system (unless you also wanted to dig up and install a clutch pedal!) Automatic transmissions are sometimes re-used, but simplified to make them more or less "direct drive" and are locked into a single gear.
Well, for starters, it's a front-wheel-drive car. There's no single drive-shaft. There's two "half-shafts", one going to each front wheel. Secondly, you would at a bare minimum still need a differential, which is built into the gearbox/transmission/transaxle. Lastly, you need gear reduction between the speed of the motor and the speed of the wheels. 300mpg.org/projects/electro-metro/transmission-for-an-electric-car/
@@BenjaminNelsonX Thanks Ben, exactly the information I have been looking for. Still trying to find out the ideal motor in todays world for a conversion. And also still trying to figure out the rights specs for such motor. I get a lot of stats and but not a lot of opinion on why one is better than another....still searching. Great job on your car btw.
dude, i bought a geo metro back in the late 2000s to convert. Never did. money money. Make sure you keep that torque real low. Those transmissions are not very strong and are not made for lots of torque.
@Donnie Fontaine depends on the gearbox you using some have gears cut and put together in a way that they say only need clutch to go from neutral to 1st and as they spinning but held together to move gear you just shift and maybe rev match as it already spinning and the gear part slides across to next gear though often not on road cars as louder than what normal ones are, often crunch or clunk noise they might make apparently
@@mlee6050 Your lack of periods and random generalization of something you don't fully understand muddied up your answer.i didn't make it past the first 10 words. some transmissions only "need" a clutch to get moving,whether forward or backwards.then if they have syncro's they can be clutchlessly shifted.electric power is different as it can be controlled quickly and accurately,unlike internal combustion engines.this is why cnc machines can do the amazing things they can do, because electronic motors can be precisely manipulated using encoders and software so im assuming when slowing down an electric motor can stop entirely negating the clutch entirely.a gas engine can not do this quite so easily
@@trillrifaxegrindor4411 I understand as I looked at all types of gears and stuff like racing people sometimes have straight cut or dog gears but not on road as it noise my school never taught us periods and stuff, it was basically capital first letter and names and full stop at end of sentence only
Because it requires specialized items (car hub motors) that are very rare, cost more than the car, and you won't be able to buy anyway because they're not in production and far too rare? Why not "just" use what's actually *available*?

Electric motor torque will (right now) Destroy standard type transmissions at the first Oppertunity of error in designs or peddle indiscression or both.
It's funny the comments that I hear from people about torque. Half the comments are that something like a forklift motor isn't powerful enough to move a car, and the other half say it will instantly destroy the vehicle. In my experience, it's neither. On the electric Geo Metro, I could pull away from a dead stop in 5th gear. I could do burn-outs in 1st gear, and the only time I ever had an issue with the driveline was when I used a cheap no-name spider coupler with it misaligned.

Hello Ben ! 👋 Well, I am one crazy guy fascinated by the torque of the electric motors & so the potential they have. Saw your whole series of converting an ICE car into an electric car. So first of all congratulations bud !! Loved it so much that it inspired me ! It's just so amazing !! You're the man 💪 Ok. I don't know if this is the right place to post this stuff but all I want is to give you my best wishes & also to have some suggestions from your side. I'm converting an ICE bike to electric one just like your car project. My bike has a manual transmission already which is but obvious & a very common thing. Now to my issues --> 1. When I am using a maximum 3000 rpm motor & connect it to the transmission, it's not slow speed of rotation or operation of the gearbox i.e. transmission. As the gears are always immersed in the oil & so if I cut the housing, there will be a big issue of oil leakage or when in operation, the oil will come out of the housing. How to seal the oil inside or solve this spillage / leakage problem in order to use the pre existing gearbox with electric motor ? How to solve this issue ? 2. Did you use oil in the 'Geometro's' transmission ? If not then is it really safe to use the gears without any oil at all ??? Won't it ruin the transmission after some rides ? Did you lubricate the transmission at least once before starting to use the vehicle regularly ? 3. Also the oil being very viscous, splashing that oil, as the motor moves the whole system, will consume some power. Won't it drop the efficiency ?? Won't it affects the power output ? 4. Using a transmission will reduce the efficiency because it introduces a bit of losses. So is using transmission really advisable ?? At least in a bike ? 5. How could you shift the gears when you were in motion ?? Is it safe for the transmission ? Was it hard to shift without clutch ? Or did it become hard to shift over the time ? 6. What is the frequency of any maintenance that is required ? Like brushes of the motor etc. ? 7. I've heard that brushed motors are less efficient than BLDC motors. So what range did you get ? & Also is it advisable to use a brushed motor ? 8. Did you do any calculations beforehand ? Or you just added a motor which was available ? What range did you get ? Top speed ? Other specifications ? Like motor power peak torque motor voltage etc...... Please feel free to contact me. My WhatsApp number. +919604010750 Thank you so much ! I will be very lucky to a receive a reply from you.
Has anyone watchedJehugarcia where the electric car gets 1200miles on one charge... I'm sure these electric motors can be coupled to a big alternator and recycling energy back. Amazing video.
Running an alternator off of the motor will just increase the load on the motor, requiring more watts to move the same distance and will not charge more than the wattage used to move it. It will actually charge less watts than it takes to drive it due to heat losses.
@@rubiconnn I have a solution to this problem. However I am very hesitant to divulge it. Because I've worked some 20 odd years on this problem to get it solved in order to build my own prototype... 1.) If it is not done just right you may have an explosion or fire hazard. 2.) Weight is the biggest contributor to failure. Doing more with less is the answer. But how it's done is the factor. (Have a great day.)

I have another question, a motor I looked at on craigslist does 1800 rpm. In the car I'd be using, 6th gear at 3000 rpm is 60mph, so would i only get 36 mph out of that motor without overvolting? Thanks!
Nabre Labre does the motor say which voltage it runs 1800 RPM? That speed is very common for an AC motor that runs from wall power. Make sure the motor you want to use is DC. If it is, increasing the voltage will proportionally increase the speed.
It is a manual or automatic car?
It's a 5-speed manual transmission, stock to the car.
You'd never want an automatic transmission for an electric car conversion. Most of the time, you'd be driving an electric version around in only one gear anyway. The automatic would be more expensive, less efficient, and mostly would just get in the way.
Electric motors behave like transmissions with an infinite number of gears. They produce their maximum torque from zero RPM and can be driven around normally without shifting gears.
Devil's Offspring I'm in a project to transform an automatic gasoline car into an electric car. We are trying to figure out how to connect the transmition to an electric motor
@@beFrah, One way of doing it is to remove the automatic transmission, and putting in a manual transmission that would have matched that car. You would then do a clutches system (unless you also wanted to dig up and install a clutch pedal!)
Automatic transmissions are sometimes re-used, but simplified to make them more or less "direct drive" and are locked into a single gear.
How much does your transmission weigh?
how much is worth and where to buy everything you need
Why don't you attach the motor directly to the driveshaft instead of gearbox? Therefore saving weight.
Well, for starters, it's a front-wheel-drive car. There's no single drive-shaft. There's two "half-shafts", one going to each front wheel. Secondly, you would at a bare minimum still need a differential, which is built into the gearbox/transmission/transaxle.
Lastly, you need gear reduction between the speed of the motor and the speed of the wheels.

@@BenjaminNelsonX Thanks Ben, exactly the information I have been looking for. Still trying to find out the ideal motor in todays world for a conversion. And also still trying to figure out the rights specs for such motor. I get a lot of stats and but not a lot of opinion on why one is better than another....still searching. Great job on your car btw.
How do you shift gears without a clutch?
Me we mind I saw the answer. I don’t really understand it but I did read it🤙🏽
300mpg.org/projects/electro-metro/going-clutchless/
Hadir lagi kita nonton..👍👍👍
dude, i bought a geo metro back in the late 2000s to convert. Never did. money money. Make sure you keep that torque real low. Those transmissions are not very strong and are not made for lots of torque.
I've commonly pulled away from a dead-stop in 5th gear. Plenty of torque. Never any issues with the transmission.
i think he means your going to strip the gears on the transmission, @@BenjaminNelsonX
@@biomecaman3514 No. Never any trouble stripping gears. Transmission in this car was always great.
use 4th (direct coupling) and reverse, the other gears are pretty much useless...
@@omegarugal9283the other gears are fun for acceleration though..and if you feel like driving it like a regular manual
hi ben how are you i hope when you have time to answer me some questions
Could someone please elaborate on how “clutchless” works? Don’t you need to disengage the motor when shifting? I’m baffled by this.
@Donnie Fontaine depends on the gearbox you using some have gears cut and put together in a way that they say only need clutch to go from neutral to 1st and as they spinning but held together to move gear you just shift and maybe rev match as it already spinning and the gear part slides across to next gear though often not on road cars as louder than what normal ones are, often crunch or clunk noise they might make apparently
@@mlee6050 Your lack of periods and random generalization of something you don't fully understand muddied up your answer.i didn't make it past the first 10 words.
some transmissions only "need" a clutch to get moving,whether forward or backwards.then if they have syncro's they can be clutchlessly shifted.electric power is different as it can be controlled quickly and accurately,unlike internal combustion engines.this is why cnc machines can do the amazing things they can do, because electronic motors can be precisely manipulated using encoders and software so im assuming when slowing down an electric motor can stop entirely negating the clutch entirely.a gas engine can not do this quite so easily
@@trillrifaxegrindor4411 I understand as I looked at all types of gears and stuff like racing people sometimes have straight cut or dog gears but not on road as it noise
my school never taught us periods and stuff, it was basically capital first letter and names and full stop at end of sentence only
why not just make the car wheel the motor?
Because it requires specialized items (car hub motors) that are very rare, cost more than the car, and you won't be able to buy anyway because they're not in production and far too rare?
Why not "just" use what's actually *available*?
why not make the sun our oven in the kitchen and use it to power the spaceship? why not use the air from flying birds to cool volcanoes and replace central air conditioning?
do you see what i did there?
its sarcasm,outlining and making fun of your question.
always use logic and intelligent thought relative to viability and do-ability of a specific topic when making suggestions.
so,in the real world logic is paramount to not sounding like a total dumbass.
in other words,think before speaking
@@trillrifaxegrindor4411 your a idiot, I have seen many electric cars with the motor in the wheel. why don't you do some research before attacking someones question.
How can I connect with you? Need help to build an electric car.
Electric motor torque will (right now)
Destroy standard type transmissions
at the first Oppertunity of error in designs or peddle indiscression or both.
It's funny the comments that I hear from people about torque.
Half the comments are that something like a forklift motor isn't powerful enough to move a car, and the other half say it will instantly destroy the vehicle.
In my experience, it's neither.
On the electric Geo Metro, I could pull away from a dead stop in 5th gear. I could do burn-outs in 1st gear, and the only time I ever had an issue with the driveline was when I used a cheap no-name spider coupler with it misaligned.
@@BenjaminNelsonX I'm the electrician ,aligning larger type high school pool pump motors to pump
Exactly for maditory opperation against immediately destructive vibration ect. You are doing fine generaly, it's just that others might not end up equaly as logical with aspersions of performances according to available area under hood & motor selections at hand with other vehicles (you know how
tollerances are & crucial safety issues involve 200-300hp success

I've been told a few time an automatic can be troublesome if not impossible to use. Can you clarify why this is ? ? ? I've got a Nissan Micra Automatic at the moment and would really like to convert it as it's a good runner other than the catalytic converter dying on me -________-
I know GM is doing a "crate engine" electric motor kit that hooks up to their hydramatic automatic transmissions.
@@louisbabycos106 Which is estimated to cost $75,000. You CAN use an automatic transmission. EV west does it with a 2 speed Powerglide transmission that has an auxiliary electric pump The hydraulic clutches won't work when the engine speed is under 500rpm so the pump kicks on to keep the clutches engaged.
buy a $50 brand new converter from magnaflow or any of the other 10,000 muffler/cat manufacturers???
why would you think you need to go electric,because of replacing a cat convertor?
Hello Ben ! 👋
Well, I am one crazy guy fascinated by the torque of the electric motors & so the potential they have. Saw your whole series of converting an ICE car into an electric car. So first of all congratulations bud !! Loved it so much that it inspired me ! It's just so amazing !! You're the man 💪
Ok. I don't know if this is the right place to post this stuff but all I want is to give you my best wishes & also to have some suggestions from your side.
I'm converting an ICE bike to electric one just like your car project.
My bike has a manual transmission already which is but obvious & a very common thing.
Now to my issues -->
1. When I am using a maximum 3000 rpm motor & connect it to the transmission, it's not slow speed of rotation or operation of the gearbox i.e. transmission. As the gears are always immersed in the oil & so if I cut the housing, there will be a big issue of oil leakage or when in operation, the oil will come out of the housing. How to seal the oil inside or solve this spillage / leakage problem in order to use the pre existing gearbox with electric motor ? How to solve this issue ?
2. Did you use oil in the 'Geometro's' transmission ? If not then is it really safe to use the gears without any oil at all ??? Won't it ruin the transmission after some rides ? Did you lubricate the transmission at least once before starting to use the vehicle regularly ?
3. Also the oil being very viscous, splashing that oil, as the motor moves the whole system, will consume some power. Won't it drop the efficiency ?? Won't it affects the power output ?
4. Using a transmission will reduce the efficiency because it introduces a bit of losses. So is using transmission really advisable ?? At least in a bike ?
5. How could you shift the gears when you were in motion ?? Is it safe for the transmission ? Was it hard to shift without clutch ? Or did it become hard to shift over the time ?
6. What is the frequency of any maintenance that is required ? Like brushes of the motor etc. ?
7. I've heard that brushed motors are less efficient than BLDC motors. So what range did you get ? & Also is it advisable to use a brushed motor ?
8. Did you do any calculations beforehand ? Or you just added a motor which was available ? What range did you get ? Top speed ? Other specifications ? Like motor power peak torque motor voltage etc......

Thank you so much !
I will be very lucky to a receive a reply from you.
Very nice 60
Has anyone watchedJehugarcia where the electric car gets 1200miles on one charge... I'm sure these electric motors can be coupled to a big alternator and recycling energy back. Amazing video.
they can't, but an alternator with a fan clutch can be used to "regen brake"
Running an alternator off of the motor will just increase the load on the motor, requiring more watts to move the same distance and will not charge more than the wattage used to move it. It will actually charge less watts than it takes to drive it due to heat losses.
Good video sir
@@rubiconnn
I have a solution to this problem.
However I am very hesitant to divulge it. Because I've worked some 20 odd years on this problem to get it solved in order to build my own prototype...
1.) If it is not done just right you may have an explosion or fire hazard.
2.) Weight is the biggest contributor to failure. Doing more with less is the answer. But how it's done is the factor.
(Have a great day.)
there is no free lunch and nothing on earth will ever produce more energy than it uses unfortunately.its one of the primary laws of physics,any "free energy device" you have ever seen is absolute bullshit
Transmission with potenciometer
Put it in fourth and leave it alone
Only if you have an AC motor that you can spin backwards for reverse
The electric car will be a toy until its made practical and affordable!
The current commercially-built electric car I am driving cost me $7,000 as a three year old car.
It meets all my daily driving needs.
@@BenjaminNelsonX Hey! Where can the rest of get one!
@@johnsavage8873 I got mine at a used car lot. You can look at Craigslist, Facebook marketplace, etc.
A used Chevy Volt is a great vehicle for a lot of people. Used Leafs can be very affordable. All depends on exactly what you are looking for.
Where you are matters a lot. California has PLENTY of used electric cars, but there are a lot fewer where I am in the Midwest. I bought mine out of Chicago (about a 2 hour drive away) as there were a lot more electric cars there.
People will sometimes buy and ship a car, or fly out somewhere to see a car.
There are also starting to be car dealerships that specialize in JUST plug-in vehicles. Here's one in Chicago: www.currentautomotive.com
Also, try joining an electric car group. There's everything from the EAA (www.electricauto.org) to Facebook groups involved in EVs. People selling a used EV often first just ask around in a group of friends.
Cool 😎
