reversing an AC motor

    I've been trying to reverse the direction of an AC fan motor without
    taking it apart and changing things.

    It doesn't have any brushes, it is just a solid core inside an
    electromagnet.
    Looking at the surface of the core, it has steel bars in a step
    pattern.

    I want to control is with a uC in both directions. I'm thinking it
    might be possible to reverse it if I change the 60Hz frequency to
    perhaps 120Hz- but if anyone knows, they could save me lots of trouble
    : )

  4. Sounds like a shaded-pole motor. Not easy to reverse!
     
  5. It's a one way motor by design. You have to use gears or pulleys to do
    the reversal.
