AI Technical Summary

Technical Problem

In the prior art, the coil winding direction of the motor winding is the same, resulting in the adjacent coil terminals in the circumferential directions in different radial directions of the motor, resulting in the problem of long terminals and confusing arrangement.

Method used

The forward winding coil and the reverse winding coil are arranged alternately so that the two winding coils adjacent circumferentially are used to be on the same radially as the second terminal connected to the N-ring, thereby shortening the length of the coil terminals and improving the rationality of the arrangement of the terminals.

Benefits of technology

The second terminal length of the winding coil is effectively shortened, the cost is reduced, and the wiring terminal arrangement is more reasonable and tidy, improving the installation efficiency and reliability of the motor.

Abstract

The present invention discloses a wiring structure of a motor winding and a motor including the same. The motor winding includes a three-phase winding assembly, and a plurality of winding coils in the same winding assembly are respectively used to connect with different wiring terminals; the first wiring terminal of the winding coil is used to connect with the phase ring of the motor, and the second wiring terminal is used to connect with the N ring of the motor; for two winding coils in the same winding assembly and adjacent to each other in the circumferential direction of the motor, one winding coil is wound from the radial inner side of the motor to the radial outer side of the motor from the first wiring terminal, and the other winding coil is wound from the radial outer side of the motor to the radial inner side of the motor from the second wiring terminal. This scheme adopts an alternating arrangement of forward-winding coils and reverse-winding coils, so that the second wiring terminals of two circumferentially adjacent winding coils for connecting with the N ring are located on the same radial side of the motor, thereby effectively shortening the length of the second wiring terminal of the winding coil, reducing costs, and making the arrangement of the wiring terminals more reasonable and neat.
