Abstract:
    A method for driving AC motor of air-conditioner includes calculating pulse width of zero cross detection when power supply is initialized, holding low level at fan driving port and calculating actual rotary speed of motor and duty ratio outputted by driving signal when motor rotary speed feedback is interrupted, energizing motor driving signal output and outputting high or low level by motor driving signal port when drop-out edge of zero cross detection is interrupted.
