Abstract
An outer rotor of a permanent magnet assisted synchronous reluctance motor includes an annular rotor core and a plurality of permanent magnets; the annular rotor core includes a central hole; the annular rotor core further includes a plurality of slots, and the plurality of permanent magnets are disposed in the plurality of slots and form a plurality of magnetic poles along the circumferential direction of the rotor core. Each magnetic pole includes three shapes of permanent magnet: a first arc-shaped permanent magnet concentric with the rotor core, a second arc-shaped permanent magnet not concentric with the rotor core, and a rectangular permanent magnet. In each magnetic pole, the three shapes of permanent magnet are symmetrically arranged along the center line of the magnetic pole, and the first arc-shaped permanent magnet, the second arc-shaped permanent magnet and the rectangular permanent magnet are sequentially spaced radially from inside to outside.
