Problems solved by technology

However, for large stator cores (with a diameter of more than 500mm), the diameter of the enameled wire in each phase winding is more than 1mm. Therefore, in the wire drawing process, if the winding of each phase is still used as a whole Pulling, not only the resistance of the winding is large, but the movement of the winding in the wire groove is not smooth, resulting in the consequences of pulling the e

Example Embodiment

[0021] Reference Figure 1 to Figure 4 The wire embedding mold for the stator iron core of the motor of the present invention includes a guide bar 501, a waist-shaped base 502, a waist-shaped cover 503, a connecting rod 504, and a locking device. An axial end surface of the base 502 away from the cover 503 is provided with a hook seat 500 connected to the wire pulling device, and the hook seat 500 is used to connect the pulling hook in the wire pulling device. The base 502 and the cover plate 503 are provided with slots at intervals. One end of the guide bar 501 is fixed in the slot of the base 502, and the other end of the guide bar 501 is clearance fit in the slot of the cover plate 503. 501 is used to hook the stator windings. From the schematic diagram of the wire embedding mold 5 of the present invention, it can be seen that at most two packages of windings can be hung on the embedding mold (each phase of the motor contains at least four packages of windings). Therefore, e...

Abstract

The invention discloses a wire inserting mold of a motor stator iron core. The wire inserting mold comprises guide strips, a kidney-shaped base, a kidney-shaped cover plate, a connecting rod and a locking device. Slots are formed in the outer circumferential face of the base and the outer circumferential face of the cover plate at intervals respectively, one end of each guide strip is fixed to the corresponding slot in the base, the other end of each guide strip is in clearance fit with the interior of the corresponding slot in the cover plate, a through hole penetrating through the two axial end faces of the cover plate is formed in the cover plate, one end of the connecting rod is fixed to the axial end face, facing the cover plate, of the base, the connecting rod and the cover plate are integrally fastened through the locking device after the other end of the connecting rod penetrates through the through hole in the cover plate, and a dragging hook base connected with a wire dragging device is arranged on the axial end face, deviating from the cover plate, of the base. By means of the wire inserting mold, wire inserting of windings with various phases is carried out in a multi-time mode, and varnished wires in the windings are prevented from being damaged.

Description

technical field [0001] The invention relates to the field of motor stator iron cores, in particular to a wire embedding mold for motor stator iron cores. 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. 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 windi...
