as our hand-cranked flashlight, if is AC motor, support the clockwise, counterclockwise to hand. If is a DC motor, only hand clockwise.

are the main differences between AC motor and DC motor, DC motor has a carbon brush and AC motor, DC motor speed feedback method, is given out by the generator voltage is converted to a digital to correct the actual speed. AC motor with pulse generator is born of actual speed pulse correction. In general better than DC AC, because of its speed can be controlled fairly accurate, and AC motor without carbon brush, the need to maintain, use more convenient.
