Motor stator wire stretcher

Abstract

The invention relates to a motor stator wire stretcher, which comprises a work table and a wire embedding mold, wherein the wire embedding mold passes through a center hole of a static iron hold under the effect of tensile force, a tensile force driving device for exerting the tensile force in the axial direction of the stator iron core and a stator iron core clamping device positioned at one side of the tensile force driving device are arranged on the work table, the stator iron core clamping device comprises a fixing seat, a connecting sleeve, a support seat and a movable clamp, one end of the fixing seat is fixed on the work table, the connecting sleeve is arranged on the fixing seat, one end of the support seat is fixed on the inner wall surface of the connecting sleeve, the other end of the support seat is arranged in the connecting sleeve and extends in the radial direction of the connecting sleeve, one end of the movable clamp is fixed on the inner wall surface of the connecting sleeve, and the other end of the movable clamp is arranged in the connecting sleeve and extends in the radial direction of the connecting sleeve. The motor stator wire stretcher has the advantages that a winding is arranged in the wire embedding mold, and the tensile force effect is exerted on the wire embedding mold, so when the wire embedding mold passes through the stator iron core, the winding is embedded into a wire embedding groove of the stator iron core.

Description

technical field [0001] The invention relates to the field of motor stator iron cores, in particular to a motor stator wire drawing machine. Background technique [0002] The winding on the motor stator is the main component of the stator core. The stator winding is connected by the coil group in a certain way to form the stator circuit, and the relative movement with the rotor magnetic flux generates an induced electromotive force to realize the conversion of mechanical energy to electrical energy. [0003] According to the shape of coil winding and the way of embedded wiring, it can be divided into two types: centralized and distributed. The winding and embedding of concentrated windings are relatively simple, but the efficiency is low and the operating performance is also poor. Most of the current AC motor stators use distributed windings. According to different models, models and coil embedded winding process conditions, the motors are designed with different winding ty...

Problems solved by technology

For the current processing flow, most of the copper wires are wound on the base mold, and then the wires are inserted manually, and there are also manual insertions without slots, the processing speed is slow, and the output is low.

It is time-consuming and difficult to install the matrix wound with copper wire windings into the stator core body manually; the manual winding is relatively loose, and the slot fullness rate should not be too high when designing the motor to affect the performance of the stator core
