A quick question regarding three phase coils connections of a motor

  1. Jun 10, 2012 #1
    Hello everyone:

    I have a quick question regarding connecting a three phase power supply to the coils of a three phase motor.

    Now I know that if you had 3 pole pairs, 6 coils 120 degrees apart around a stator, that each diagonally adjacient coil gets connected in series and each of these series of two coils get connected to one of the three power supply phases. The series coils are shown in the attached picture so you can see what I am talking about.

    But what if I wanted 8 coils, 4 coil/pole pairs. How would I connect this to a three phase supply so that the magnetic field rotates dragging the rotor around and around as the motor is supposed to do?

    Thanks for any help you guys could give me. I really appreciate it.

    Stephen
