Description

A winding device for motor stator windings

technical field

The invention relates to the technical field of motor stator winding winding, in particular to a winding device for motor stator windings.

Background technique

The stator winding refers to the winding installed on the stator of the motor, that is, the copper wire wound on the stator. Winding is a general term for a phase or the entire electromagnetic circuit composed of multiple coils or coil groups. Motors can be divided into two types: centralized and distributed according to the shape of the coil winding and the way of embedded wiring. The winding and embedding of the centralized winding is relatively simple, but the efficiency is low and the running performance is also poor. Most of the current AC motor stators use distributed windings. According to different models, models and process conditions of coil winding, the motors are designed with different winding types and specifications. According to the number of magnetic poles of the motor and the distribution of the windings, the stator winding forms the relationship between the actual number of magnetic poles and can be divided into two types: explicit and implicit.

The windings of the stator winding of the existing motor mainly include the method of directly winding the copper wire on the stator of the motor, and first winding the copper wire on a module, and then fixing the wound copper wire coil to the copper wire and fixing it to the stator.
