AC Motor
AC motor employs alternating-current power. The rotary speed is relatively difficult to control, and the rotating direction can't be controlled.
Features:
The electric current interacts with the magnetic field and rotates the coils when the current passes through the coils (conducted by non-insulated parts);
The rotating coil keeps rotating under inertia when it rotates to the insulated part where no electric current is conducted;
The electric current is conducted again when the coil finishes an entire circle of rotation, and it keeps circling in such manner. In comparison, a real motor alters the direction of electric current with commutators.
