ELECTRIC MOTOR, COMPRESSOR AND REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/068052
Kind Code:
A1
Abstract:
An electric motor (100), a compressor and a refrigeration device. The electric motor (100) comprises: a stator core (110), wherein the stator core (110) has an inner cavity and comprises a plurality of stator slots (112), the number of stator slots (112) is Z, and the outer diameter of the stator core (110) is D1; and a rotor core (130) arranged in the inner cavity, wherein the outer diameter of the rotor core (130) is D2, the number P of poles of the electric motor (100) satisfies 6≤P≤8, the number Z of stator slots satisfies 36≤Z≤48, and the outer diameter D1 of the stator core (110) and the outer diameter D2 of the rotor core (130) satisfy (aa). Limiting the size range of the stator core (110) and the rotor core (130) of the slot-pole combination electric motor (100) can improve the output capability of the electric motor (100) and improve the energy efficiency of the electric motor while reducing noise, such that the electric motor (100) having such a structure can meet the requirement of a high-power compressor.
