Description

Coil Winding Machine for Cylindrical Linear Motor

technical field

The invention relates to a coil winding machine for a cylindrical linear motor, which is a winding machine capable of directly winding a wire cake in a motor groove of a cylindrical linear motor.

Background technique

The traditional winding machine for winding motor coils consists of a roller, a handle, and a base. One end of the wire is fixed on the roller, and the coil can be wound by shaking the handle. After the coil winding is completed, it is installed on the motor. in the slot. However, for cylindrical linear motors, since the motor slot is an annular closed slot with the notch facing inward, the traditional method of winding the coil first and then installing the coil into the motor slot is difficult to implement, because the diameter of the wound coil larger than the diameter of the notch of the annular groove. The current solution is to divide each annular groove into two parts along the circumferential direction for processing, which will destroy the magnetic circuit of the motor and increase the difficulty of motor assembly.
