Self-heat-dissipation rare earth permanent magnet synchronous motor

Abstract

The invention discloses a self-heat-dissipation rare earth permanent magnet synchronous motor. The motor comprises a machine bin , wherein a front machine cover and a rear machine cover are arranged at two ends of the machine bin correspondingly, a filtering assembly is arranged at the end, away from the machine bin, of the outer side of the front machine cover, a bearing B is arranged in the center of the end, away from the machine bin, of the front machine cover, connecting rods are evenly arranged at the end, away from the front machine cover, of the inner side wall of the machine bin, andbearings A are arranged at the ends, close to each other, of the connecting rods. The motor is advantaged in that the front machine cover, the machine bin, the auxiliary assembly, the fixing assemblyand the rear machine cover are used in cooperation, when the motor is disassembled for maintenance, excessive fixing screws do not need to be disassembled; when the front machine cover and the rear machine cover are installed, the front machine cover and the rear machine cover do not need to be manually supported to keep alignment of screws and screw holes, only the insertion rods need to be inserted into the insertion grooves, convenience of disassembly or assembly of the motor is greatly improved, and stability of connection between the front machine cover and the machine bin and between therear machine cover and the machine bin can be further improved through the auxiliary assemblies.

Description

technical field [0001] The invention relates to the technical field of AC motors, in particular to a self-radiating rare earth permanent magnet synchronous motor. Background technique [0002] AC permanent magnet synchronous motor has attracted more and more attention because of its small size, light weight, high efficiency and energy saving, and the starting torque and overload capacity of rare earth permanent magnet synchronous motor are stronger than ordinary synchronous motor, so it is widely used used in industrial production. [0003] During the use of the current rare earth permanent magnet synchronous motor, most of the outside air enters the motor through the gap between the machine compartment and the front and rear covers to cool down the inside of the motor, but the gap between the machine compartment and the front and rear covers is limited. , and currently only a set of fans are installed on the motor shaft inside the synchronous motor, it is impossible to imp...

Problems solved by technology

[0003] During the use of the current rare earth permanent magnet synchronous motor, most of the outside air enters the motor through the gap between the machine compartment and the front and rear covers to cool down the inside of the motor, but the gap between the machine compartment and the front and rear covers is limited. , and currently only a set of fans are installed on the motor shaft inside the synchronous motor, it is impossible to improve the self-heating effect of the rare earth permanent magnet synchronous motor; However, most of the traditional heat sinks are directly welded on the outside of the machine compartment. At this time, the effect of the heat sink will be greatly reduced, so that the heat dissipation effect of the synchronous motor cannot be further improved; while the current rare earth permanent magnet synchronous motor is for It is convenient for air to flow inside the motor, and there are gaps and through holes on purpose. Although it is convenient for air flow, when the motor is not in use, the dust in the external environment will slowly enter the interior of the machine compartment with the air flow and cover it. On the internal components of the motor, it affects the actual effect of the subsequent use of the motor; at the same time, the front cover and the rear cover of the current rare earth permanent magnet synchronous motor are fixedly connected to the machine compartment through multiple sets of fixing screws, which is very difficult to disassemble and install. It is inconvenient, and it is impossible to further improve the stability of the connection between the front and rear machine covers and the machine compartment
