Embodiment Construction

[0041] The best mode for actualizing the coil end fixing method of the stator according to the present invention will be described in detail below with reference to the drawings. The coil end fixing method of the stator according to the present embodiment generally includes a step of bundling the coil ends of the stator into a mesh shape, a stitching thread treatment step, and a painting treatment step. These steps will be described in sequence.

[0042] First, the tightening process will be described. The outline of the tightening process is in the figure 1 Indicated. In the tightening process, such as figure 1 As shown, the stator 1 is rotated by a specified angle each time, and the wire supply nozzle 5 that can move in the axial direction of the above-mentioned stator 1 and supply the wire and can move in the axial direction and radial direction of the above-mentioned stator 1, and pull The mutual action of the hook 4 pulling the thread supplied by the above-mentioned...

Abstract

An object is to provide a stator coil end fixing method capable of firmly fixing a coil end without making a knot in a thread while effecting lacing with respect to the coil end of a stator. Lacing with respect to the coil end (2) of a stator (1) is effected by interaction between a thread supply nozzle (5) and a hook (4). A sewing start thread (9s) is sewn into the coil end (2) and a sewing end thread (9e) is passed through both a loop (Rn) formed at the end of the lacing and a loop (Rn-1) formed last but one and is pulled and simply knotted, whereby the sewing end thread (9e) is processed. And, the sewing end thread (9e), which is simply knotted, is subjected to varnishing, whereby the simply knotted portion is solidified.

Description

technical field [0001] The invention relates to a method for fixing coil ends protruding from both end faces of a stator core. More specifically, it relates to a stator coil end fixing method capable of fixing the coil ends without forming a wire knot while tightening the coil ends of the stator. Background technique [0002] The stator, which is a component of the motor, is formed by attaching coils to slots formed in the stator core. Coil ends are formed on the stator as portions where the coil protrudes from both end surfaces of the stator core. This coil end may come into contact with the rotor or housing when the motor is constructed. Therefore, the coil ends are bundled together with wires (by so-called binding), and then varnish is applied to fix the coil ends. [0003] Among them, the binding is performed by braiding the thread and sewing the loop ends into a mesh shape. In order not to loosen the part sewn into a mesh shape, it is necessary to properly handle th...
