    Default wiring crompton parkinson motor

    any body wire a Crompton Parkinson ph1 240v motor ?
    this motor had a 7 core wire for reversing the motor
    it also has two extra wires coming out of the motor to the motor terminal box
    it has a capacitor start
    how do you connect for single direction running

    The information should be on the inside of the cover plate. I suggest you post this in the transformers, phase converters and VFD forum.

    Is there a data plate on the motor? there are a different number of poles in an induction motor according to intended running speed. 2850 RPM @ 50hz would be a 2 pole motor. If it's 1425 RPM it would be a 4 pole motor.

    Changing the pole connections reverses the motor. When I've set up single phase motors to reverse it's only needed four wires out to a 2 pole changeover switch rather than seven.

    Thanks for the replies
    Wish there was information on the cover plate
    The two extra wires that come out of the motor
    Are What I do not understand
    Poles marked A and Z go to the capacitor
    Might move as suggested to a different forum
