    Hello,

    Are these the correcting windings for a 3-phase induction motor? Are the windings wrapped in the correct direction? I think they are, but I'm not sure.

    I am not an expert, but I believe the "B" winding must be wound the opposite of A & C.

    I'd think it was OK as drawn, but I'm not an AC motor expert.

    Yeah, I did a little added research at lunchtime.
    It looks fine.

    Hi,

    Did you happen to find any websites that showed the direction of windings?

    I don't think the direction of the windings is important because you don't know the relationships of the three phase power feeding the motor. That's a common problem with a three phase motor-you won't know which way it spins until you hook it up. If its backwards switch any two leads.

    I built and tested the above motor. The direction of the windings are indeed correct.
    :)
