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.

Abstract: A fan motor structure is provided. A fan is disposed within an accommodating hole at a center of a body. A permanent magnet and a printed circuit board (PCB) provided with plural coils are respectively disposed between an upper ring and a base of the body. An axial air gap is formed between the coils and the permanent magnet. A bearing is disposed between the upper ring and the base. The fan blades of the fan extend from the periphery of the accommodating hole toward the center of the fan. An axle center of the fan overlaps with that of the body. The coils after being supplied with a current create a flux linkage with the permanent magnet. Due to the flux linkage and the axial air gap between the coils and the permanent magnet, the upper ring is forced to rotate, thus driving the fan to rotate.

Abstract: The present invention relates to a low cogging and easy-to-downsize spindle motor structure. The motor is an axial magnetic flux spindle motor comprising a stator assembly and a rotor assembly. The stator assembly comprises a deck for seating the rotor assembly and at least one bearing placed on the housing of said stator and between the stator and the rotor. The outer periphery part of the bearings is the stationary part; with the inner part of said bearings being the rotating part. A cylindrical shaft is located in the center of the rotor. When the thin windings of stator are excited with current, a rotating magnetic field is created, forcing said rotor into rotation, and as a consequence, bringing the spindle into rotation that generates motor output needed to drive loads.
