ABSTRACT:
A permanent magnet motor includes stator, rotor, and shaft; multiple rotor magnetic poles are disposed on the rotor; each rotor magnetic pole contains an arc surface and a first inclined section and a second inclined section extending respectively from both sides of the arc surface; a trap is formed between two second inclined section of two abutted rotor magnetic poles connected by a tangent section; multiple magnets are respectively disposed in each rotor magnetic pole; both ends of each magnet being disposed at where close to two second inclined sections; and a central portion of each magnet is indented inwardly towards a center of the rotor to effectively upgrade performance efficiency of the motor.
