    Hello, I have an industrial 5 HP Baldor motor I would like to use for a Quincy air compressor a recently aquired. The problem is, the motor spins CW, and i need CCW. The motor doesn't have the wiring to hook it up as CCW. I have changed a couple (older) motors over by taking them apart and turing the brushes, but this motor is different then those it seems, I have attactched some images of the insides of the unit. Any help would be very useful, especially if it ends with getting it to turn CCW!
    Thanks,
    Chris

    Is it a 3 phase motor?

    appears to be single phase AC. Check your model number against the manufacturer. Not all are reversible.

    It looks like an AC synchronous motor to me. Does it have a dataplate on the motor? Is it dual voltage? Is it reversible? The leads should be numbered. That numbering is fairly standardized between different motors of the same type (i.e., dual voltage, reversible). Just find another Baldor motor of the same type. John

    Sorry, it slipped my mind. Its single phase, 230 volt. I am in ohio this week for work, won't be back until friday. I rember reading type 377, frame 203?. Man, I really hope I can do this, it would save me alot of cash!
