Abstract: A motor according to an embodiment of the present disclosure is provided with a housing in which a stator core is press-fitted therein.
Refrigerant supply grooves to distribute and spray refrigerant are formed in an inner circumferential surface of the housing.
Therefore, refrigerant can be smoothly supplied, without having to increase a size of the motor or add a separate component.

Abstract: Disclosed herein are a stator and a method for manufacturing the same. The stator according to embodiments of the present disclosure includes an insulating part and a plurality of stator coils each having two ends electrically connected to form one joint portion. The insulating part is configured to cover at least respective parts of the joint portions, and to provide a distance between neighboring joint portions. Accordingly, a partial discharge caused by a surge between the joint portions of the stator coils may be prevented, allowing operational reliability of the stator to be increased.
