http://www.oddparts.com/acsi/defines/poles.htm This is the technical definition on what a pole is, in layman’s terminology it’s the speed of the motor which is determined by the number of poles, 2 poles 3600 rpm’s, 4 poles 1800 rpm, 8 poles 800 rpm’s, these speeds are with no load and are a little slower when a load is place on it.

I know that is true for multi speed electric motors, but automotive motors only have 2 poles, positive and negative, motor speed is handled by a motor controller. Some automotive motors only have 1 pole for a connection, that is usually positive, the negative is carried by the case of the motor. HTH
