Patent ID: 7808143

Claim:
A permanent magnet motor comprising a stator containing a ring body and multiple stator magnetic poles; each stator magnetic pole protruding from interior of the ring body, and an accommodation room being formed in each stator magnetic pole; a rotor related to a plate approximately indicating a circular form and provided in the accommodation room and keeps an air gap from each stator magnetic pole, the rotor being disposed with multiple rotor magnetic poles, and each pole being disposed with a magnet; each rotor magnetic pole being disposed with an arc surface, and a first inclined section and a second inclined section extending in sequence from both sides of the arc surface, a slope of the first inclined section being smaller than that of the second inclined section, a trap being formed between two second inclined section between two abutted rotor magnetic poles connected by a tangent section, both ends of each magnet being disposed at where closer to two second inclined section; and a central portion of each magnet being indented inwardly towards a center of the rotor; and a shaft disposed at the center of the rotor and made an integrated part with the rotor.
