A circulating water pump motor for a dishwasher facilitating heat dissipation

Abstract

A circulating water pump motor for dish-washing machine is convenient for heat dissipation, which comprises a stator core, front and rear machine covers clamped and fixed at two ends of the stator core, bearing holes are formed at central positions of the front and rear machine covers, front butt joints are connected with front end covers through a plurality of front connecting ribs, front heat dissipation holes are formed between adjacent two front connecting ribs, the rear machine cover comprises a rear butt joint and a rear end cover, a rear clamping seat is arranged at an end surface of the rear butt joint, a rear end surface of the stator core is clamped and installed in the rear clamping seat, the rear butt joint is connected with the rear end cover through a plurality of rear connecting ribs, rear heat dissipation holes are formed between adjacent two rear connecting ribs. The front and rear heat dissipation holes constitute direct and effective heat dissipation channels, air convection between the inside and outside of the motor is promoted, and the operating temperature of the motor as a whole, especially the stator core and other heating components, is significantly reduced.
