Title:
STATOR, ELECTRIC MOTOR, COMPRESSOR, AND REFRIGERATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/097919
Kind Code:
A1
Abstract:
Provided in the present application are a stator, an electric motor, a compressor, and a refrigeration apparatus. The stator comprises: a stator core comprising a plurality of stator teeth that are arranged at intervals, a stator slot being formed between every two adjacent stator teeth; stator windings, which are wound around the stator teeth and at least partially located in the stator slots; and insulation layers, each of which is arranged in the stator slot, is located between the stator windings and the stator teeth, and divides the stator slot into two regions, the stator windings wound around different stator teeth being located in the two regions of the insulation layer. The insulation layer comprises a first insulation layer configured to separate the stator windings from the stator teeth, and a second insulation layer configured to separate the stator windings wound around different stator teeth, with either end of the second insulation layer being connected to the first insulation layer to divide the space enclosed by the first insulation layer into two regions. According to the stator provided by the present application, the slot filling rate of the stator is increased, and the assembly efficiency of the stator is improved.
