Abstract

The invention discloses an external ventilation and heat dissipation structure of an air-cooled vertical permanent magnet motor, and the heat dissipation structure comprises a fan, an air inlet wind scooper, a motor base air inlet, a motor base inner cylinder, motor base heat dissipation ribs, a motor base outer plate, a motor base air outlet, a shaft extension end cover, and end cover heat dissipation fins. The fan and the air inlet wind scooper are sequentially installed on the motor base air inlet, the motor base heat dissipation ribs are welded on the outer surface of the motor base inner cylinder along the radial circumferential direction, and the motor base air inlet and the motor base air outlet are sealed through the motor base outer plate; a radiating air channel is formed between the inner surface of the motor base outer plate and the outer surface of the motor base inner cylinder, the shaft extension end cover and a non-shaft extension end cover are respectively arranged at the two axial ends of the motor base outer plate and the motor base inner cylinder, and the end cover radiating fins are arranged on the outer surface of the shaft extension end cover. According to the invention, the problems of external ventilation and heat dissipation of the vertical permanent magnet motor are effectively solved, the safe and reliable operation of the permanent magnet motor is ensured, the maintenance cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of permanent magnet motors, and relates to an external ventilation and heat dissipation structure of an air-cooled vertical permanent magnet motor, in particular to an air-cooled permanent magnet motor external for vertical motors that adopts side ventilation and cooperates with end cover cooling fins to dissipate heat. Ventilation and heat dissipation structure. Background technique [0002] In recent years, with the continuous development of rare earth permanent magnet technology, permanent magnet synchronous motors have become more and more ideal drive motors used in various modern industrial sectors. It has high overall efficiency, low maintenance, excellent speed regulation performance, and large overload starting capacity. advantage. When the ambient temperature is high and the load is heavy, if only natural cooling is used, sometimes it cannot meet the heat dissipation requirements, so air cooling or water coo...
