Will I be correct if I say that a 4 pole motor makes use of its rotor's magnetic field better than a 2 pole even if the magnetic mass are the same?

Can't be apple to apple. 2 pole against a 4 pole. Rotor size differences, motor wire gauge difference, etc.

If you drive enough with both of type of motors regardless of kv, you can tell a difference in behaviour between the two.

So 4 pole better or more poles better?

Understood. As I said, you have the real world experience and that's what matters. The proof is at the dragstrip!

Yea that is one of the places you can see the two pole having an advantage over the 4 pole motor. But if I were to race offroad, I would definitely run a 4 pole motor.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>
