ABSTRACT:
A miniature DC brushless motor having a radial air gap and a single coil with axial winding includes a stator having a single coil with axial winding, a rotor with a permanent magnet, and a control circuit. Two terminals of the single coil are electrically connected to the control circuit that controls the conducting direction of current of the single coil to generate alternate rotational magnetic fields, thereby driving the permanent magnet to turn.
