Method for parallel winding of outer rotor via stator iron core and winding device thereof

Abstract

The invention provides a parallel winding method capable of parallel winding of the outer rotor via a plurality of leads and convex teeth of a stator iron core in high efficiency and a winding device. Via making the outer rotor be in a back and fro rotation in a certain angle via a stator iron core, and making the outer rotor be in a back and fro movement toward a shaft direction simultaneously, the front end of a sprayer nozzle is made to surround the convex teeth of the stator iron core, and the sprayer nozzle is made to rotate with the axis as the center, the rotation and the sprayer nozzle's surrounding of the convex teeth of the stator iron core are synchronous, and a lead supply device is made to rotate, preventing leads from being twisted, every circle the sprayer nozzle surrounds the convex teeth makes the spray nozzle move toward the shaft direction, the leads are orderly winded around the convex teeth. The sprayer nozzle is provided with a seam-shaped opening with a width roughly equal to the diameter of the outer side of the leads and a length of a row of leads in a parallel arrangement, or is provided with a plurality of openings in parallel in a row and allowing for passing through of only one lead, the length direction of the seam-shaped opening or the parallel direction of the plurality of openings are made to be a linear direction of the circumference of the winded convex teeth, thereby making the sprayer nozzle rotate.

Description

technical field [0001] The present invention relates to a parallel winding method for a stator core for an outer rotor and a winding device thereof. The parallel winding method is a stator for an outer rotor that has a plurality of protruding teeth protruding radially at certain angular intervals toward the outer periphery. The iron core is wound in parallel. Background technique [0002] A stator core for an outer rotor used in a rotating electrical machine such as an electric motor has a plurality of convex teeth protruding radially at a certain angular interval on the outer periphery. A method in which the wire can be drawn out from the outer circumference of the nozzle to wind the wire around the protruding teeth. [0003] On the other hand, in recent years, in order to reduce the resistance of wires, a motor that winds a plurality of wires in parallel and supplies current to the wires has been increasingly used. However, if a plurality of wires are pulled out from the...

AI Technical Summary

Problems solved by technology

However, if multiple wires are pulled out from the nozzle and wound around the nozzle in parallel on the outer circumference of the protruding tooth, there is a problem that many wires are twisted and the whole becomes thicker, making it difficult to wind in high density.
