Motor Poles versus Coils

[gtranquilla]

I was under the impression that the motor pole count is always equal to the motor coil count...
but these motors are sold as 22 pole yet have 24 coils......
Can someone please explain this?

They're probably counting the number of magnets on the rotor as "poles". They aren't poles in correct parlance. IIRC, there's always one more, or one less, magnets than poles so the motor doesn't pole-center and not start under electronic commutation. How they come up with two is beyond me. Or, it could just be plain wrong, wouldn't be the first time for HK.

Electro 2 ..... thanks.... very good information.
