Abstract
A motor, including at least a stator, including at least a stator core and a coil winding, and a rotor, including at least a rotor core and multiple permanent magnets. Multiple wire receiving grooves are disposed on the stator core. The permanent magnets are disposed on the rotor core. The ratio between the number of teeth of the wire receiving grooves and that of the permanent magnets is 3:2. Every two or three of the permanent magnets form a group of permanent magnets. A gap is disposed between adjacent groups of permanent magnets. The groups of permanent magnets are circumferentially distributed. Magnetic polarities of the permanent magnet are alternatively distributed in a N phase and a S phase. Difference in an electric angle between centers of polarities of adjacent permanent magnets in one group is between 150 degrees and 170 degrees.
