Abstract

See full text

A motor, a compressor, and a refrigeration device are provided. The motor includes a stator assembly and a rotor assembly. The stator assembly includes a stator core provided with a stator slot. The rotor assembly includes a rotor core and a permanent magnet. The stator core is sleeved outside of the rotor core or vice versa. The permanent magnet is arranged on the rotor core. By limiting the relationship between the distance between the stator core and the rotor core, the length of the permanent magnet in its own magnetization direction, the number of the stator slots, and the intrinsic coercivity of the permanent magnet, it is possible to adjust the strength of the demagnetization reverse magnetic field generated by energizing the motor.
