ABSTRACT:
A motor module includes a bearing housing having a loading base, an electric unit, a bearing, and a magnetic rotor unit disposed on the bearing. In addition, a protruding portion is extending from the loading base, and the electric unit includes a printed circuit board (PCB) and sensing elements, wherein the PCB is utilized for disposing the loading base thereon. Moreover, signal circuits and motor windings are formed on the PCB around the loading base, the sensing elements are disposed around the motor windings, and the bearing is disposed at the protruding portion. Besides, the magnetic rotor unit is disposed on the motor windings, keeping a gap with the PCB; therefore, when electric current passes the motor windings, the magnetic rotor unit and the motor windings generate a flux linkage induction, so as to drive the magnetic rotor unit to rotate relative to the PCB.
