Embodiment Construction

[0032] like Figure 1-6 As shown, the present invention provides a motor casing, wherein:

[0033] The motor casing 2 is a cylindrical structure, including an inner wall 2-4 and an outer wall 2-3, and a wall along the cylindrical structure is also provided between the inner wall 2-4 and the outer wall 2-3. An axially extending groove 2-1, the cooling fluid can pass through the groove 2-1. In the present invention, a groove structure is provided between the inner wall and the outer wall of the motor casing, and a cooling liquid (preferably water) is introduced into the groove to effectively dissipate heat and cool the motor casing, so as to effectively Cool and dissipate the heat generated by the stator and rotor inside the motor casing during operation, improve the heat dissipation capacity of the motor, effectively reduce the temperature, and improve the efficiency of the motor, thereby improving the operating efficiency of the air compressor system and reducing power consum...

Abstract

The invention provides a motor casing, a motor and a compressor, the motor casing is of a cylindrical structure and comprises an inner wall and an outer wall, a groove extending in the axial direction of the cylindrical structure is further arranged between the inner wall and the outer wall, and cooling fluid can be introduced into the groove. According to the invention, the motor casing can be effectively cooled, so that heat generated during the operation of the stator and the rotor in the motor casing can be effectively cooled and dissipated, the heat dissipation capability of the motor is improved, the temperature is effectively reduced, the efficiency of the motor is improved, the operation efficiency of an air compressor system is improved, and the power consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a motor casing, a motor and a compressor. Background technique [0002] Air compressor motors are mainly divided into asynchronous motors and permanent magnet motors. Since asynchronous motors are designed based on rated points, when the motor speed decreases, the motor efficiency and power factor drop sharply. As a commonly used power source equipment, the air compressor has an average load rate of 57%, which shows that the asynchronous motor is not the best matching motor. The permanent magnet synchronous motor can be adjusted by frequency conversion, and has the advantages of low temperature rise, high power density, good starting performance, high light load efficiency, small size and light weight. The industry started a large-scale energy-saving transformation in 2014, using permanent magnet motors to replace asynchronous motors. The transformation was basically complet...
