Washing machine motor

Abstract

The invention discloses a washing machine motor comprising a stator and a rotor. The stator has an annular main body; wire contact boards and baffles are arranged at the upper end surface, with an upper pin box body, of the inner side wall of the main body; the baffles are arranged at the inner sides of the wire contact boards; and an incoming-outgoing dividing plate with two ends having differentheights is arranged between each two adjacent wire contact boards. The rotor includes a flat-barrel type shell; the lower end surface of the shell protrudes inwardly; and an arched ring is formed atthe connection part between the bottom end surface of the shell and the side wall of the shell. Besides, an opening portion for flow guiding is formed in the bottom end surface. The washing machine motor has characteristics of being easy to package and transport, having good heat dissipation performance, realizing stator winding easily and having good protection effect of the stator winding, having high assembling stability, carrying out wiring conveniently, having the high strength of the rotor structure, and being easy to process.

Description

technical field [0001] The invention relates to a direct-driven washing machine motor. Background technique [0002] With the development of technology, the direct-drive washing machine emerges at the historic moment, and because it takes up less space than the traditional washing machine, the characteristics of low noise are more and more popular. The direct-drive washing machine motor includes an inner ring-shaped stator and an outer-coated barrel-shaped rotor. The middle of the end face of the rotor is connected to the drive shaft, and the stator is generally fixed to the outside through the pin seat on the inner wall. In the existing direct drive motor, since the stator pin seat is relatively lower, the part of the rotor and the fixed transmission shaft can only protrude outward in order to avoid interference with the stator pin seat. The uneven lower end surface of the rotor also leads to the occupation of the motor. The space is relatively large, and since it cannot b...

AI Technical Summary

Problems solved by technology

During maintenance and overhaul, due to the non-uniqueness, the stator can be installed even if it is rotated at a certain angle, resulting in a decrease in assembly accuracy, and it is prone to excessive deviation from the original position, making wiring difficult and resulting in reassembly

The rotor of the motor also has poor structural strength due to unreasonable structural design, and it is difficult to process multi-segment bosses.
