Method and device for coiling motor stator

Abstract

A retaining jig is provided comprising a retaining part, a displacing means, a winding machine and a core guide. The retaining part moves together with a nozzle performing a cyclic motion, and holds a wire paid out from the nozzle; the displacing means transports the wire in the outer circumferential direction of a stator while the wire is held; the winding machine has a releasing means which releases the hold on the wire transported to a predetermined position in the outer circumferential direction by the displacing means; the core guide is further disposed opposit to the opening of stator slot, which guides the wire W into the stator when the wire held by the retaining jig is guided in the outer circumferential direction relative to an opening in the stator. A small and high-output motor is obtained by expanding a cross-section area of a coil, eliminating a dead zone in a slot caused by a passing nozzle of a wire supply device, and thereby to smoothly and exactly conduct the winding and inserting of a wire into the slot of a motor stator from an opening of the slot without damaging the wire in particular.

Description

technical field [0001] The invention relates to a winding method and a winding device of a motor stator for eliminating winding dead areas to increase motor output power. Background technique [0002] Figure 15-Figure 18 Shows the existing method of winding the motor stator. [0003] In the figure, the stator 1 winds the electric wire W around the wound portion 3 of the slot 2 . The feeder 31 of the winding device for winding the electric wire W on the wound portion 3 of the groove 2 is provided with a pair of lead-out pipes 33 protruding radially from the upper part of the shaft 32 through which the electric wire W is inserted. The shaft 32 moves through the stator 1 in the axial direction, and performs an oscillating motion of reciprocating and rotating a predetermined angle in the circumferential direction. [0004] In order to wind up the electric wire W using the feeder 31 , the shaft 32 moves up and down in the axial direction and reciprocates in the circumferential...

AI Technical Summary

Problems solved by technology

[0009] However, in the technology disclosed in this Japanese Patent Application No. Hei 11-071246, from the viewpoint of improving motor performance, the slot opening 4 of the stator 1 is extremely narrow, so it is impossible to send out the lead-out pipe 33 from the slot opening 4. The electric wire W is smoothly and surely inserted into the groove 2. In addition, when the electric wire W is inserted into the groove opening 4, the electric wire W is in contact with the protrusion 5 protruding from both sides to the groove opening 4 side. Here, There is a problem of scratches when inserted into the groove 2 while rubbing
