Motor insulating framework with asymmetrical tooth parts, motor stator, motor and compressor

Abstract

The invention provides a motor insulating framework with asymmetrical tooth parts, a motor stator, a motor and a compressor. The insulating framework comprises an annular part (1), multiple tooth root parts (2) and tooth parts (3), wherein the multiple tooth root parts (2) are arranged on the inner wall of the annular part (1); the tooth parts (3) are connected with the free ends of the tooth root parts (2); each tooth part (3) comprises a bottom surface (31) and a top surface (32) which are arranged oppositely in the axis direction of the framework, and a first side surface (33) and a second side surface (34) which are arranged oppositely in the circumferential direction of the framework; the top surface (32) comprises a top end (35) with the highest axial height, a first transitional surface (36) connected between the top end (35) and the first side surface (33), and a second transitional surface (37) connected between the top end (35) and the second side surface (34); and the axes of the top end (35) and the first transitional surface (36) and the second transitional surface (37) relative to the top ends are asymmetrical. By virtue of the insulating framework, the windward area is enlarged, intensity of pressure is lowered, wind loss of air flow is lowered, and resistance force is lowered.

Description

technical field [0001] The invention belongs to the technical field of electric motors, and in particular relates to an insulating skeleton of an asymmetric electric motor with teeth, a motor stator, a motor and a compressor. Background technique [0002] At present, the inner wall of the frame tooth part of the motor insulation frame structure in the prior art is usually designed as a left-right symmetrical structure, such as Figure 1-3 As shown, it often has the following deficiencies: [0003] 1. The compressor motor forms a certain resistance during high-speed operation, which in turn increases the loss of the motor (such as image 3 shown); after the skeleton and stator, stator and rotor are assembled, such as image 3 As shown, the balance weight in the rotor assembly is prone to airflow wind wear loss at the teeth during the rotation process; [0004] 2. During the rotation of the rotor, because the airflow is blocked by the teeth of the skeleton, the airflow path ...
