In this video we will talk about a DC motor which is the ideal choice for many applications where it’s needed: reliabilit, low maintenance, less noise, speed control and low cost
In the specific, we are going to see how does a brushless DC motor works.
We can assume already by its name, that this type of electric motor has no brushes.
As we have already seen in our previous video about the working priciple of DC motors, the brushes are sliding devices which allow the electricity to flow into the copper coil of the engine.
The brushless motor have no sliding elements on the collector, so, this completely solves the problem of maintenance and replacement of brushes and other electrical contacts.
Unlike the common DC motors, that use brushes for their functioning, brushless motors do not produce sparking or friction noises within them.
This is a very interesting feature of brushless motors, becouse allows them to be suitable for use in environments where sparks are dangerous. For example in environments where ignitable gases are present.
This type of motor has a rotor with permanent magnets, it could not be otherwise, since there are no contacts on the rotor, as we already said.
Its stator has electromagnets excited by windings in coils.
This is an important difference compared to the traditional brushes DC motor, since the latter can have both stator and rotor composed of electromagnets, to increase the magnetic fields and therefore have an higher mechanical power density by unit of weight of the motor.
The torque of the brushless motor is due to the magnetic interaction imposed by the electromagnets on the permanent magnets.
There is a precise sequence of excitation of the electromagnets which imposes to the permanent magnets an angular movement, which is always in the same direction, and it is as constant as possible under the same excitation.
When electricity flows into coil 1, the opposite poles of the rotor and stator are attracted to each other.
When the rotor is getting closed to the coil 1, the electricity flows in the coil 2. When the rotor is getting closed to the coil 2, the electricity flows in the coil 3. Later in the coil 1 the electricity will flow again, but with opposite polarity. This process is repeated continuously inside the engine ensuring a constant rotation of the rotor.
Obviously the sequence is cyclical and the rotor continues its rotation until it is powered, repeating the sequence, from time to time.
To be more specific: the sequence of excitation of the electromagnets inside the stator is such that the magnets of the rotor are attracted to the electromagnets without never reaching them, as the excitation is always and only of those coils "not yet reached".
An example to better understand this principle is represented by the dog race in which a hare is placed in front of the greyhounds at such a distance to be seen but never reached.
In this metaphor, the dogs represent the rotor that follows the magnetic flux generated in exact sequence in the coils of the stator.
In the case of more coils, always multiples of 2, it makes sense to use a sequence that uses them all, to increase the magnetic flux to which the permanent magnets are subjected, and turning off only the opposite electromagnets.
This simple foresight increases the torque, that is the power that the motor can supply, without substantially modifying its design criteria.
The greater the number of coils, the smoother is the rotation of the rotor, which will thus have a constant torque.
But how does our brushless motor know the precise moment in which to excite the correct sequence of electromagnets which allow continuity of the rotary motion?
For this purpose, an electronic controller is typically used. This controller has a sensor to detect the exact position of the rotor magnets and thus decide which coil energize by following the right excitation sequence.
The modern brushless motor sensors uses the Hall effect.
In this animation we can observe the configuration of a standard sensor.
This is a simple 2-pole device that can drive 2 or 4 or 8 or more electromagnets in the just seen sequence.
This, is instead the representation of a classic circuit layout with protection diodes. The presence of diodes is necessary to protect the sensor from negative self inductance, in case we need to suddently block the power supply from one of the coils.
There are basically 2 families of brushless motors. Those with external stator and those with internal stator.
We can summarize the main strength points of the brushless DC motor...

The two inactive coils in your animation could also be energized in reverse polarity to "repel" the magnets as they have already passed, thus giving the motor even greater torque.

This helped a lot! I entered my first R/C car with a Brushed motor race a couple weeks ago. I watched the pro guys racing their cars with Brushless motors and wondered why the noise the cars made was super low!! I thought it was because of the cars were going so fast that the sound decimated. But the explanation of a brushed vs. a brushless motor sound made a lot of sense! Thank you!

Great video. I have a cordless drill that is brushless. This explained why it seems to have more torque. I'm sold on this design.
Thank you Mike for your comment! Let's not forget that brushless motors are better adapted, generate no friction, produce less heating and provide better performance. Plus the maintenance is significantly reduced, which comes down to dusting and there is no need to replace worn brushes.

I started buying the XR versions of my dewalt 20V tools, and noticed they dont overheat like the brushed motor versions. For homeowners the brushed is fine, but if you need it for work in a factory or trade get the brushless.
Dear Alex thanks for your comment If you are interested give a look to our website :www.jaescompany.com and please let us know what do you think about our video induction motor ua-cam.com/video/EcbHEOIVGcg/v-deo.html
I would still recommend brushless for home owners since they tend to be treacherous on tools. For one, if they get wet, it's not an automatic death sentence for the tool. Second, they are less susceptible to over torquing And, when the tool gets dusty, a quick squeezes on the trigger seems to clear out the debris without affecting the tool itself. The only problem I found is sudden stops can wrench your arm and hurt like crazy.
Yea my personal XR Dewalt tools have been completely reliable in commercial construction applications since 2014. The DC motors are the best.
@@fwingebritson I would recommend brushless for homeowners as well, but if you put a dewalt or Milwaukee brushless drill in front of someone just looking to wall mount their TV or repair furniture once a month they might be intimidated by the increased price. Homeowners are also less likely to be forced to work outside or in dirty areas.
@@AlexFlockhart That would depend on the home owner. Now if we are talking apartment/condo dwellers, you have a solid point, but the average home owner sees themselves as "weekend warriors" and doing things around the house is part of their work out.
I do HVAC and a lot of equipment is switching over to DC motors / inverters and freq drives. This is very informative. Thank you.

As a tool guy I purchased many Ryobi tools that are now brushless motor tools. My older ones lasted a long time but now when I purchase a new brushless motor tool, it burns up rather quickly. I have also heard from others that they have a problem with new tools that claim to be brushless not lasting very long. I've decided to go to whatever brand does not have brushless motors.
This is interesting. Thank you for the knowledge. Subscribed!

Not so sure on the lower cost statement. Usually BL tools are pricier.

Greatly informative, thank you. Are there any specifications for RPMs and horsepower? Or do you use a different rating system?
Hello. Thanks for your question! These specifications depends on the model.

I like the analogy of the dog race with the motor's rotation. It's helpful.
Can't say I've ever heard of an electrical engine . Only electric motors .
Very whiity Rick. That's a good one
We humbly apologize for this terrible mistake! We are really sorry and we promise, you'll never have to go through it again. Please watch and comment this ua-cam.com/video/EcbHEOIVGcg/v-deo.html and visit our website www.jaescompany.com/ Thank you sir.
I caught that too.
And the Marine Corps put me in "Motor Transport" . I often wondered why they called it that.
Confusing.
Very useful, thank you!
How is this DC motor when you need to use AC pulses to move it? Just because we use transistors mosfet and create square wave to power coils we use alternating currents so it should be AC nod DC motor.
I believe it's due to the DC control. Even though any brushless motor is going to be AC powered.
You could use the term AC induction both for synchronous and asynchronous types. Both BLDC and AC induction is correct. In forklifts it's advertised as an AC motor, though some have the cheap option of using DC hydraulic motors 🤮

Right. The science in this video is completely not accurate. Modern day brushless motors are not DC motors at all. They are actually very closely related to a typical three-phase AC motor. We use a speed controller it takes DC voltage it converts it to a three phase voltage at a frequency desired for the RPM wanted. It's actually very closely related to a synchronous AC motor. What was described in this video would require at least six Leeds coming out of the motor to do what he explained. Might want to go back to school
I'm pretty sure the use of DC is in terms of application. If someone has a DC supply and needs a motor they will buy a motor listed as DC. They don't care that the motor is running on AC they only care that their DC supply voltage will work.
I believe it is a DC motor because the pulses are controlled DC. If you throw raw ac at it, it wont work at all. The output from the controller may look AC, but its not. The pulses only go from positive to negative because its chasing the magnets that have a north and south. if there were only two magnets it would be + - + - + -. But if there are six magnets, its + + + - - -
Very well explained
Thanks for the video

What software did you use to make that illustration?
Not the same one used for translating to Engrish is my best guess.
just what I was looking for! thanks
No engine in a motor and it's HALL effect not HAL effect (as in a hallway)

I figured it was simply because it was a synthesized voice.
Yeah, a little slip. I caught it but understood everything anyhow. Just needed some proofreading.
Super ji
extremely well explanation

An engine producers power! A motor uses external power. Car guys confuse this too.

In everyday parlance we tend to use "motor" for electric engines, but a motor is still an engine. Oxford Dictionary: Engine - a machine with moving parts that converts power into motion.
Spin one of your motors unpowered and put a voltmeter across the terminals and say that
I really enjoyed this video. Thank you very much for posting it. It was very informative to me with regards to products that I am developing.

I think im losing my hearing - I could have sworn he said "and low cost" at the begining.
For real lol 15 bucks for a brushed rc car motor and 100 bucks for a brushless one
He also repeats it in the end around 5:45 for instance, Though not sure how it works out with the cost of the brushes vs the cost of permanent magnets. As those are the 2 biggest differences in components and so the biggest difference in production costs as well.
@@TheYdyp apart from the comment that he made about low cost I think he's spot-on with Logistics
Don Din....Here in The Great White North (Canada) brushless motors are double the cost of brushed motors.
@@rogertycholiz2218 what's your point?
This was very easy to follow and very helpful thanks R R
thanks for your comment, please give a look to our ua-cam.com/video/EcbHEOIVGcg/v-deo.html maybe can be interesting for you too
I'm just glad I had my teeth converted to brushless teeth. Thank God, no more brushing required.
Great video, didn't get to technical in a technical. Good place to start learning more about brushless motors and motor controllers.

do yall have any that work under water
As long as all the wiring and boards are insulated from the water, there shouldn't be any reason why not. You will want to make sure the motor bearings are well sealed as well.
