Compressor motor, motor stator and motor insulation skeleton of compressor motor

Abstract

The invention provides a motor insulation skeleton. The motor insulation skeleton comprises a skeleton outer wall, a skeleton inner wall and a plurality of skeleton winding parts, wherein the skeleton outer wall and the skeleton inner wall are annularly circled, the plurality of skeleton winding parts are connected between the skeleton outer wall and the skeleton inner wall, gas channels are formed in the skeleton winding parts, inlets of the gas channels are positioned in the skeleton inner wall, and outlets of the gas channels are positioned in the skeleton outer wall. When a motor rotor rotates, gas can flow from the skeleton inner wall to the skeleton outer wall through the gas channels, and then flows from the outer wall of a stator to an exhaust end, so that a flow area is increased, and the oil return effect of a compressor is increased; additionally, the gas flows through the skeleton winding parts, so that a part of heat generated by a stator winding can be removed, the cooling effect on the stator winding is achieved, the motor efficiency is improved, and the service life of a motor is prolonged. The invention further provides a motor stator on which the motor insulation skeleton is installed, and a compressor motor on which the motor stator is assembled.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor insulation frame, a motor stator and a compressor motor. Background technique [0002] The motor is composed of two main parts, the stator and the rotor. The motor stator is generally insulated by an insulating skeleton. The insulating skeleton is an injection molded part that is arranged at the end of the motor stator and has a wire-passing structure design. There is no gas diversion structure designed on the existing insulating frame, which makes the gas circulation inside the motor poor, affects the oil return effect of the compressor, and the heat dissipation of the stator winding is poor. Contents of the invention [0003] Based on this, it is necessary to provide a motor insulation frame that improves the internal gas flow capacity of the motor and the heat dissipation efficiency of the stator winding and a motor that assembles the motor insulation frame to addres...
