Abstract

The invention discloses a permanent magnet synchronous motor based on an efficient heat dissipation mechanism. The permanent magnet synchronous motor comprises a base, an inner heat dissipation assembly, an outer heat dissipation assembly, a damping assembly and a moving assembly, wherein the top of the base is fixedly provided with a motor body, and the interior of the motor body is rotatably provided with a motor shaft; the inner heat dissipation assembly is installed in the motor body, and the outer heat dissipation assembly is installed at the top of the motor body and connected with the motor shaft; the damping assembly is mounted at the bottom of the base; and the moving assembly is installed at the bottom of the damping assembly. When the device operates, air in the motor body is disturbed through heat dissipation blades, heat dissipation is carried out on the motor body, meanwhile, heat dissipation is carried out on the outer surface of the motor body through the outer heat dissipation assembly, a heat dissipation effect is further improved, in the rotating process of a motor shaft, a cooling fan is driven to transversely reciprocate so that the cooling range of the cooling fan is greatly expanded, and vibration generated during operation of the device can be reduced through the damping assembly.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a permanent magnet synchronous motor based on a high-efficiency heat dissipation mechanism. Background technique [0002] The permanent magnet synchronous motor provides excitation with permanent magnets, which makes the structure of the motor relatively simple, reduces the cost of processing and assembly, and saves the collector ring and brush that are prone to problems, which improves the reliability of the motor operation; and because no excitation is required current, without field losses, increasing the efficiency and power density of the motor. Permanent magnet synchronous motor is composed of stator, rotor and end cover and other components. The stator is basically the same as the ordinary induction motor, and adopts a lamination structure to reduce the iron loss when the motor is running. The rotor can be made solid or stacked with laminations. The armature winding can ...
