Problems solved by technology

[0002] With the increase of the capacity of the large permanent magnet motor, the loss inside the motor also increases correspondingly, which causes the temperature rise of the motor to be too high, which in turn affects the safe and stable operation of the motor
By mixing ventilation and cooling in the radial or axial direction of the motor, although it can meet the heat dissipation requirements of large permanent magnet motors, the effective material utilization rate of the motor is reduced due to the existence of radial ventilation grooves, thereby reducing the weight of the motor. and cost increase

Abstract

The invention provides a stator for a motor, a motor and a ventilation cooling method thereof, wherein the stator for a motor includes: concentrated windings, at least two wedges are arranged in the gap between adjacent concentrated windings blocks; wherein, the at least two wedges are distributed in a staggered manner on the concentrated winding to form a first ventilation path. The embodiments of the present invention can effectively cool the concentrated winding, and effectively restrain the concentrated winding in the circumferential direction through at least two wedges, further prolonging the life of the motor and improving the reliability of the motor.

Description

technical field [0001] The invention relates to a stator for a motor, the motor and a ventilation cooling method thereof, in particular to a stator based on a concentrated winding permanent magnet motor and a ventilation cooling method thereof. Background technique [0002] With the increase of the capacity of the large permanent magnet motor, the loss inside the motor also increases correspondingly, which causes the temperature rise of the motor to be too high, which in turn affects the safe and stable operation of the motor. By mixing ventilation and cooling in the radial or axial direction of the motor, although it can meet the heat dissipation requirements of large permanent magnet motors, the effective material utilization rate of the motor is reduced due to the existence of radial ventilation grooves, thereby reducing the weight of the motor. and cost increases. Contents of the invention [0003] Embodiments of the present invention provide a stator for a motor, a m...
