    Does anybody can help me how to control rotation directions of the synchronous motor?
    Here, i have a relay that comes from a main ciruit. i use relay to switch the current booster of the main circuit. the main circuit is about 9v DC.
    the AC synchronous motor i plug it to that relay and 220v AC source that i i use for analog timing, but it rotates randomly. How to solve it?
