Box-type high-speed asynchronous motor

Abstract

A box-type high-speed asynchronous motor comprises a motor rotor, a motor stator, a bearing and a cooling system, and the cooling system comprises a shutter cover plate arranged on the side face of the shaft extension end of the motor stator and a cooling device arranged on the top of the non-shaft extension end. The motor stator comprises a stator iron core and a stator coil, punching sheets of the stator iron core are square punching sheets, adjacent punching sheets are rotatably arranged at an included angle of 120 degrees, a radial channel hole from inside to outside is further reserved in the end part of the stator coil, and the axial position of the radial channel hole corresponds to a rotor balance disc of the motor rotor; compared with a conventional round punching sheet, the square punching sheet is larger in area, better in heat dissipation condition, simple in whole cooling structure and free of external water source for heat exchange. In addition, the bearing inner cover is in a positive pressure environment, so that the probability that bearing lubricating oil leaks into the motor is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a box-type high-speed asynchronous motor.

Problems solved by technology

Although in the technical scheme of the utility model, the iron core and the rotating shaft are integrated, the end ring and the iron core are welded together, a plurality of axial hollow grooves are evenly processed on the outer circle of the iron core, and the outer circle of the iron core is evenly divided into strips of equal width as the magnetizer and The conductor can withstand high centrifugal force and has no guide bars, thereby avoiding the failure of the rotor guide bars to break when the motor is running at high speed, and further ensuring the safety of the motor; The overall layout does not involve
