Here’s what I’ll say: if you’re a contractor, or someone who will be using the drill/impact or whatever it is constantly - buy the brushless. You’ll get longer battery life, and the tools won’t overheat as easily, as well as you may get a slight power advantage over brushed depending on the brand. However, if you’re someone who only occasionally needs to use the tools - just buy the brushed. It’s cheaper, and still get really solid build quality depending on the brand. Plus, if your brushes wear out they’re easy as heck to replace.
The brushed does have one and only one advantage over the brushless: the cost and simplicity in replacing parts. When a brushless motor dies: you have to buy a new tool, if a brushed motor dies: you probably just need to replace the brushes.
That's what she said
@Stanley McNulty she said that too
As a contractor I say correct. But brushless motors last substantially longer. 5x for real
@@PS-zw4yc why do you work about brushes? Have you worked with it and how can you get a job at it or where?
@@pipony8939 the what?
Amazing well explained, needed this info getting into hobby grade RC
To the point, logical and well explained. One of the most informative YT vids i've seen in a long time. Thanks
Thank you
Craig Morgan not saying it wasn't adequate, but would you be raving about the same content from Ed Asner instead of Katy?
I rest my case
DREW JEERS you’re cringe
I still don’t know the difference.
Thank you for explaining that!👍😊
Very nicely explained thanks
Good videos and presentation....now i can learn how to make my own racing drone
Short and sweet thanks
Thanks for the informative video, & explaining The Difference between Brush & Brushless motors.
The weakness in the brushless tools are going to be the cheap electronics that drive the motor. They will likely be the failure point. The little computer also typically has pre-determined notched speeds so you don't get continuously variable control. You also get the added trigger lag as the chip tries to figure out how far the trigger's pressed in with most brushless tools. Companies are eager to switch to brushless though because it can make tools lighter and cheaper to manufacture/ship from wherever they slap them together. If brushless designs resulted in larger/heavier tools, despite not having brushes that can wear out that tech would remain a novelty and would probably never be adopted on a large scale.
I have a brushless ryobi and put it thru hell. works till this day.
remember..the plastic housing isn't the same as they used to be.
Your right about the speed control much smother with brushes, some tools will always be made with brushes.
nice cup of tea
Thank you
Very helpful vid
Thanks lady
Well said Katie
Bldc does not generate heat, but the controller does
Nice to see u
We had lots of yellow brushless drills for our electrical crew when I worked as an electrician installing equipment at our local Chevron refinery, typically they would only last a year. The few older brushed units actually lasted longer. They were never fixed, only replaced. They would just stop working, seemingly from an internal electrical issue. I’m not going to say those drills were poor, those drills took a beating from us. A brushless unit is usually bigger and therefore heavier too, and the extra cost seems to be over inflated by a long shot. I’ve never priced out the cost to have the electronics in a brushless unit replaced, but I suspect that they are ridiculously overpriced. All my power tools at home are brushed, if I was still working in the trade and had to supply my own power tools I would consider brushless, but I know they still break.
thnx a lot!!!!!!
I don't know about brushless motors. This lady is gorgeous!
The big problem with brushless tools is their very complex and delicate control electronics. They cannot be repaired and the entire circuit must be replaced. Brushed motor tools are extremely robust and their 4-pole versions are very powerful, which is why they still exist. many dewalt xrp series tools 15 or 20 years old working today.
Agreed. Cost myself $15 for replacement brushes on my makita drill
@@blaked8963 the probleme is with some motors where the brushes are inside the motor housing like fore some chinese cheap cordless drill for example ,so it's complicated to fix them, and we have to change the whole motor
I say that's a negative. My Ryobi!
a brand people hate. That brushless cordless drill was a beast.
dropped it from so many heights etc.
Drilled a lot of 1/2 holes with it.
thru 2inch square tubing 1/4 in thick.
I put that cordless thru hell. it's still working.
I say that's a negative.
put a brushless motor in the hard body plastic as they did the old cordless.
If brushless can't be repaired and regular motors can.. why even get it repaired? buy a new one?
XRP are very delicate. I've seen them fall from 10-15 ft and give out.
Take a brushless sawzall to a pipe with water in it and you run the chance of ruining the sensor.
I love brushless for clean work areas, but brushed tools have remained superior in harsh wet and abusive environments.IMHO
Thanks

Brushless generator looks more durable than brush by design. The Brushed Generator's conductors between stationary and other in motion - must be connected to conducting the electricity. Brushless generator doesn't need that, since copper coils are stationary.
The major advantage brushless is less friction and less loss as brushes start to wear/down- grade performance immediately. This is well know in other applications that have long used in competitive use to point that brushed is not seen in them any long. Brushless isn't really that new in applications. Cost is the down factor but has gone down which is why you see it offered in lessor applications now.
Great
Oh yea
hi sir, i just have 2 questions
1. which of the two is better for aquariums?
2. can a brushless motor run 24/7?
thank you in advance
Brushless always.
Depends on how large the motor is and the load constant load it endures. Your main concern is heat. If kept cool and not under much load a brushless dc Motor can run 24/7
Sir...?
I connected my golf battery to me golf trolley the wrong way around and the result was that my trolley dose not work anymore. Do you know what happened and is there a quick fix you can help me with.
Probably your best hope is for a blown fuse. After that it could be anything, sorry.
bad luck next time get someone who knows what they're doing to help
As i spin the brush motor with my hand i cant help but notice a fraction noise, should i lube it?
Check the bearings, lube or change them, otherwise should be ok
the probleme is with some motors where the brushes are inside the motor housing like fore some chinese cheap cordless drill for example ,so it's complicated to fix them, and we have to change the whole motor
In my (personal) experience the overcomplicated wiring and requirement of a computer chip causes brushless tools to be much less durable than brushed. I believe the word “durable” is used wrong when talking about the lack of physical contact in a brushless motor. The brushes wearing out on a tool is normal and still takes 5-10 years with heavy use. This doesn’t lower the durability at all in my opinion as the brushes are consumable. It’s more like replacing the batteries in a remote than the remote breaking.
You could make a brushless tool in a glass housing and it would shatter the moment you drop it. Would that tool be considered more durable? If you look at brushes as consumables then they become the more durable tools due to their simplicity. I feel a lot better when one of my brushed tools falls off of a roof simply because I know it will still run fine after. The brushless tools just don’t hold up to as much physical abuse.
My 2 ¢
yes.
the plastic used now is not the same.
back then they could take a beating.
brushless or regular dropped from the same height will give out.
depends on how the tool lands now.
it's sort of like a combustion car vs an electric car like an electric car sort of doesn't have the problems of a combustion engine but it is a whole lot more expensive to repair if something does go wrong and it's a lot cheaper to replace parts (if common car) on an combustion car. so durability imo is how cheap it is to repair and if you have minimal problems after the repair
Cory chase??
what do the brushes do?
Makes the rotary power connection to the armature windings via a commutator. This electro magnetises the armature in opposition to the fixed field winding electromagnetic field, hence producing rotary mechanical torque. I hope this helps.
@@petcatznz Or you could say.... Electricity is passed through the brushes like a wire. But wires won't work because they'd get tangled up. The brushes allow the electricity to be transmitted to a spinning shaft/commutator then to the armature.
Very impormative now iknow the diference between brushed and brushless motor.
my brush motor drone is better than my brushless one :)
Which drone is yours?
@@paulorosa506 i got a contixo f-18 brushless and very good ,easy to fly.going out now .LOL
but its not faster and the electrics will go
Exactly, brushless motors are cheap, designed to throw away.
brushless motor how much cost
450-1500
M O R A T T U P U L I bugs 3 has brushless I think and it costs about £50
"In perpetual physical contact with the shaft"
Really?
I read a review on a Milwaukee tool site and one guy said his brushes drill was more durable than the new brushless he purchased. Someone else said the brushless is very sensitive to moisture compared to a brushed version, maybe if its foggy out or working near the coast.
Has anybody else experienced the differences like that?
No, he lied
I have a Milwaukee brushless drill. It has incredible torque, does not burn out brushes (hasn't got them), and really does not care about water. Sounds to me like you have it exactly backwards. Excessive moisture in the air could coat the commutators and they would stop working; also, brushed motors eventually develop a "varnish" on the commutators and must be polished from time to time.
I have a Milwaukee cordless brushless circular saw, that’s 3 1/2 years old and it’s in for repair, some days it wouldn’t work, and other days it would work, it’s a piece of shit I’ve got tools makita with brushed motors that are 18 years old and still working fine, brushless motors are junk.
Brushed makes more torq
Really? Why ?
@@SpadaFer Brushless needs usage of back emf to have torq
No one seems to factor in the electronics failing. That's the weak link in a brushless tool... Where as brushed tools just need their brushes replaced once per decade or so for a few dollars.
@@SpadaFer brushed motors can have way more torque than brushless motors but brushless motor have a way higher rmp than a brushed motors .a brushed motor usually have 25,000-40,000rpm and brushless motors usually have 30,000-65,000rpm .
@@xxzenonionnex7658 I just bought a brushed one that is 400 ft lbs. It seems overbuilt for it's power. Brushless ones seem weaker for the amount of power they have.
You never said anything about the power and torque each gives off
Since brushless motors are more efficient, that probably means that you can make more power using less energy. Pretty much every electric car on the road uses brushless motors.
pourquoi on comprend pas
brushless is the better choice... but more expensive
Doesn't the commutator take an AC signal and convert it to DC? 🤓
The BATTERY supplies the dc to the 3phase controller, which outputs a pulsed sequence in 1-2-3 order to the three phases of the 3 phase motor ( which is a three phase ac motor only using a more square wave form rather than the sinusoidal wave from 3phased mains power) "brushless dc" IS 3phase AC
like everything does that
The cost of electronic parts is NOT the reason a brushless motor is MORE EXPENSIVE ! The parts are FAR cheaper than the cost of the brush assembly. Why then are brushless motors more expensive ?? because ... @#!$%^%$# I don't know.
"Why then are brushless motors more expensive ?"
They contain extremely powerful neodymium magnets and neodymium is a "rare earth" found pretty much only in China.
@@thomasmaughan4798 The magnets aren't that expensive. The tiny coils inside a brushless motor have to be hand wound, and a brushes motor coil is machine wound. So basically one can be readily and cheaply spit out of a industrial machine. The other requires somewhat skilled hands on labor.
Lynch brushed motor 93%, Maxon brushed 92% their brushless 86% so not sure why you're claiming brushless are more efficient? - Brush controllers are both more efficient and cheaper
Rather a lot depends on the number of poles and commutators. In the illustration, there's only two commutator bars which means as you apply full current to the rotor, most of the time the magnetic poles are too far away from the magnets to impart much torque but are nevertheless drawing current. Adding more poles and commutator bars allows the current to flow into a winding that is very nearly at the optimum location for peak torque; but if you do that then each winding cannot occupy much space so that limits the horsepower of the motor.
Not mentioned in this nearly useless video is that brushless motors can operate at high torque and very low, or even zero rotational speed; a thing that would quickly burn out the commutator of a brushed motor.
Peak efficiency is obtained with a pulse width modulated electronic speed controller so that you are not simply slamming the electromagnets with full power in succession; a thing that creates some mechanical stress, modest inefficiency and rather a lot of radio frequency interference.
Lol Brushless dc is a marketing term. "Brushless dc" is nothing more than 3 phase AC! The only thing "dc" about them is that they are powered by a dc BATTERY!
And brushes
Brushless motors typically use three phases, but need not be limited to three. They are indeed similar to a 3 phase AC motor; the main differences being that "brushless motors" typically use permanent magnets whereas AC motors typically use induction. Because of that induction, AC motors can only be used at the frequency for which they are designed and that produces a rotational speed (RPM) that is not intended to be adjustable. A brushless motor using permanent magnets is usually infinitely adjustable in RPM from zero up to some specific upper limit.
@@thomasmaughan4798 is Tesla car good? Why because if the battery explode it takes 24 hours to shut it down? Does it has brushless motors? Does it work better than average car or it's all marketing
@@pipony8939 "is Tesla car good?"
Good depends on definition. Many people consider Tesla very good.
"Why because if the battery explode it takes 24 hours to shut it down?"
If the battery explodes it obviously shuts down instantly.
"Does it has brushless motors?"
All electric vehicles, except some golf carts, use brushless motors. They offer high torque, low maintenance, and continuously variable RPM (rotational speed).
"Does it work better than average car or it's all marketing"
EV's are better at some things; particularly in cities where you spend a lot of time stopped, frequent acceleration and deceleration. Hybrid automobiles combine the best of both worlds; a Ford Fusion hybrid for instance engages both the electric motor and the gasoline engine to merge onto a freeway; superb acceleration like you have a 'muscle car", but gets 40 miles per gallon or was it 60? I drove one around Minnesota and was amazed.
Two big downsides to EV's is battery cost and temperature; they don't like it too hot and they don't like it too cold. Brushless motor works fine in cold; doesn't like very hot (above the "curie temperature").
@@thomasmaughan4798 thank you
Hey beautiful
You could feel that Katie was thinking “please God fuc*ing Kill me now” as she was regurgitating dialogue for a topic she could care less for. Personally, I thought it was great!
*couldn't care less
Not worth the price difference
Brushless motor’s don’t last longer, that’s bull shit.
I speak for many of guys on here,I'm sure. Darken the glasses, change hair color and do... Lastly tighten the shirt. Cute girl. Let's see more of her
Indeed, thanks for representing us...it's true :):):)
this video is dumb do brushless motors even have disadvantages except for being more expensive
Like what?
@@princenoah21 they are lighter, more powerful, spin faster, more torque, more efficient, last longer
Truuuee
For small motors brushless is superior in nearly every way. ALL disk drives use brushless motors, all computer cooling fans use brushless motors. They will run for YEARS with zero maintenance.
Where it can be less effective is larger motors or hot areas. Heat deactivates permanent magnets (but usually the magnetism returns once they cool down). So a motor to be used in a hot area can still be brushless but needs electromagnets for both rotor and stator.
Currently I'm debating whether to get a brushless hammer drill that has less torque power but burns less battery energy vs the brushed hammer drill that has more torque but consumes more battery energy 🤔
The brushless has 405 lb of torque. The brushed has 450 lb of torque. I'm thinking I might just go ahead and get the brushless to save on battery life. But I'll have to sacrifice torque power. Damn that sucks.
Great info thank you
So, did you get one, how its going ?)
