Abstract

The invention aims at providing a heat dissipation structure of a motor stator. The heat dissipation structure comprises a motor housing, a stator iron core, a stator coil, an insulation heat-conducting layer, and heat conducting wires. The insulation heat-conducting layer is arranged at the bottom of the stator coil; and a plurality of heat conducting wires are arranged at the other surface of the insulation heat-conducting layer. A leading pressing plate is arranged at the top of the stator iron core; two groups of stator pressing pieces are arranged outside the stator iron core; any one oftwo groups of stator pressing pieces includes two symmetric semi-circular rings; a gap opening is formed between the two symmetric semi-circular rings of any one group of stator pressing pieces; and the two groups of stator pressing pieces are arranged in parallel. A plurality of ventilation openings are formed in the side surface of the motor housing. The heat dissipation structure has the following beneficial effects: when a permanent-magnet brushless motor uses the heat dissipation structure, the overall cooling capacity of the motor is enhanced under the circumstance that the size is not increased obviously; and with the centralized cooling way of multiple motors, the overall size of the equipment is reduced, the usage requirement of the motor is ensured, and the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the mechanical processing field, in particular to a heat dissipation structure for a motor stator. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy. It uses the stator winding to generate a rotating magnetic field and acts on the rotor to form a magnetoelectric force rotating torque. The motor is mainly composed of a stator and a rotor. The direction of the current-carrying wire in the magnetic field is related to the direction of the current and the direction of the magnetic field line (magnetic field direction). The working principle of the motor is that the magnetic field acts on the force of the current to make the motor rotate. [0003] The permanent magnet brushless DC motor is a DC motor with a magnetic field established by one or more permanent magnets. Its performance is similar to that of a separately excited DC motor with constant excitation current, and the s...
