A VERY important note that isn't a topic in this vid is that a higher pole count will have less shaft rotation before back emf occurs to the esc, thus making startup alot smother/steady without a sensor from a dead stop. That's one of the reasons why brushless non sensored crawler motors usually have a high polecount. This matters less on a basher but I wouldn't want to run a 2pole these days since the startup is significantly better on 4poles or higher making a high geared 2pole setup really hard to launch. Thanks for the vids! Love the real science behind everything!
let me ask if there are 2 motors DC of the same size, one with 2 poles and the other with 4 poles, which motor rotates faster and which one will bear the load better. thank you very much.
Another fantastic vide…: tutorial ! Super clear and non-ambiguous. A subscription must ! Question I have is whether a higher pole count would possibly equate to a smoother, more quiet running motor ? Such as a Hacker A50 10-pole vs a TPP 4050 4-pole ? Background : looking for the “Bentley” boat drive units for ascale mahogany speedboat
It really depends on motor design and the esc used, however you may find that the higher pole count motor seems to operate smoother and with better control at slow speeds.
@@RCexplained Thank you for taking the time to answer Ryan. Very kind. I would agree that a higher pole count would appear smoother. Subjectively. But the ESC may well be just as- or perhaps even more important than the motor iself here…
You might have an error in your graphic. 60,000 x (4/2)
Thanks, correction noted in description!
I would like too add. I do find most of Ryan’s video’s very interesting.
I don't know how more rc enthusiasts aren't subscribed. I love your videos!
Glad you like them! Thanks for the comment RCnurse.
This Video Greatly Helped Me!
Glad it was helpful!
I believe you put the wrong eRPM for the 4 pole at 1:50
yes, thanks, correction in description
Another great video, keep them coming. Thanks.
Thanks, will do!
Thanks for explaining ryan. This helps alot
Happy to help!

im trying to find out what motor to buy and this helped alot.
Thanks for all the info Ryan, very helpful as always.👍🏼🚗
Glad it was helpful!
No love for outrunners? Why do huge outrunners tend to have a pancakes shape with a very large diameter and small length with 50+ poles?
I'm having an issue with 12 pole motors not being compatible with some esc. Why is that?
let me ask if there are 2 motors DC of the same size, one with 2 poles and the other with 4 poles, which motor rotates faster and which one will bear the load better. thank you very much.
Can you suggest a few resources, textbooks which can explain these topics in detail?
6-pole sensorless motors are perfect for crawlers.
Was hoping you’d mention motor “turn”

Why don't they have 3 and 4 pole motors?
Poles have to be in pairs of North / South
@@RCexplained but you can get a model train with a 3 or 5 pole motor?
I'm not sure about model trains, however, it does not sound like they use 3 phase brushless motors.
@@RCexplained they are brushed motors I think.
Makes sense, then yes the brushed motors can be 3 pole.
So basically this video was a waste of time. Ryan said it doesn’t matter what pole your motor is. Look at the other specifications of the motor.
What a waste of time...
