How to determine the pole count of a mmm motor

Can anyone point me in the right direction to where I can find out how many poles a motor is? I am talking about the line of castle motors and others as well. I have a eagle tree data logger that I'm trying to setup for various vehicles and motors I'll be using in the future..............


Thanks ahead of time.........

All the Castle/Neu motors are 4 pole, the older CMS-36 series motors are 2 pole

That was simple. How about the traxxas and novak ballistic 550 5.5 motors ?? Thanks !!

Both 2 pole

Cheers

Most 1/8 car motors are 4 pole, include Castle, Tekin, Neu, Leopard, Medusa, etc.

Novak makes only 2 pole motors by far.

1/10 cars use more 2 pole motors.

Very few manufacturers make car motors more than 4 pole, include TenShock(6 pole) and some German stuff.

Castle's new 1/10 motors are 4 pole

I've got a medusa 540 4 pole motor (pretty sure....lol)

Yes Medusa are 4 pole
Neu 4 pole
Feigao 2 pole
Novak 2 pole
Tekin T8 motors 4 pole
all other Tekin to my knowledge are 2 pole as
Roar approved 540 sensored motors are all 2 pole to the best of my knowledge

You just have to count the magnetic heavy point when you do one complete rotation of the rotor (hope it means what it means in french...). Usually, a 4 poles motor will have 12 points, 2 poles 6 points.

I'll have to find the thread where we discussed viewing the "actual KV" (and pole count) from the MMM "learning" the motor for torque control. I would think that info would be a solid way of valuing a motor.

Going to try to find it...

Got it :-)

12 points because motor stator have 12 slot ~~~

I have the pole count for all the motors I have in my "database" if it helps: http://scriptasylum.com/rc_speed/data_motor.html

Of course, but 4 poles motor have generally or always 12 slots.

Pretty much true, but Medusa as an exception, their motors have 9 slot stator and 4 pole rotors.

And they are 12 points too, so it's not the slot count determine the points, it's 3x rotor pole count.
