Abstract
A permanent magnet motor and a compressor are provided. The motor has a rotor, a stator core, and a stator winding. A plurality of coupled coils are disposed on the stator core. The coil includes a first type coil and a second type coil. The stator winding is a three-phase stator winding. Each phase of the stator winding is provided with three joints In each phase, a first joint and a second joint are disposed on the first type coil, a third joint in the stator winding of each phase is disposed on the second type coil. The permanent magnet motor provided by the present disclosure can improve the efficiency of the motor and reduce noise.
