Abstract
An inner-rotor type motor includes an iron core having a magnetic yoke portion and a plurality of magnetic pole portions. The magnetic yoke portion includes an assembly hole through which a shaft extends. A plurality of magnetic pole portions is arranged around the magnetic yoke portion. The iron core includes a plurality of receiving grooves. Each receiving groove is formed between two adjacent magnetic pole portions. The permanent magnets are received in the receiving grooves. At least one abutting member is coupled with an outer periphery of the shaft and includes a radial extension portion having a guiding surface. The guiding surface abuts against at least one of permanent magnets. The iron core, the permanent magnets, and the at least one abutting member of the rotor are received in a compartment of the stator. The shaft of the rotor is rotatably coupled to the stator.
