Embodiment

[0050] Hereinafter, embodiments related to a coil mounting method and a coil mounting jig will be described with reference to the drawings.

[0051] The coil mounting method of this example is a method for manufacturing a stator for a rotating electrical machine by mounting the coil 8 on the teeth 71 of the stator core 7 . Such as Figure 8 , Figure 9 As shown, the coil 8 is formed such that the winding portions 82A, 82B, and 82C of the rectangular wire 801 wound in a substantially quadrangular shape overlap three or more layers along the radial direction R of the stator core 7, and the closer the coil 8 is located in the radial direction R The winding portions 82A, 82B, and 82C on the outer peripheral side have a larger width toward the circumferential direction C of the stator core 7 . In addition, the number of winding layers in the radial direction R of the winding portions 82A, 82B, and 82C can be, for example, 3 or more and 10 or less.

Abstract

A coil mounting method for manufacturing a stator for a rotating electric machine by mounting a coil 8 on teeth of a stator core. When the coil 8 is attached to the teeth, the plurality of winding portions 82A, 82B, and 82C are clamped in the radial direction R, and the one of the plurality of winding portions 82A, 82B, and 82C arranged closest to the radial direction R is constrained in the circumferential direction. The innermost winding portion 82B on the inner peripheral side, and the outermost winding portion 82A arranged on the outermost peripheral side in the radial direction R among the plurality of winding portions 82A, 82B, and 82C. Then, the innermost winding portion 82B and the outermost winding portion 82A are relatively moved in opposite directions in the circumferential direction, whereby the coil 8 is deformed and attached to the tooth.

Description

technical field [0001] The present invention relates to a coil mounting method and a coil mounting jig for manufacturing a stator for a rotating electric machine by mounting a coil on teeth of a stator core. Background technique [0002] As a method of manufacturing a stator for a rotating electrical machine, there are a method of arranging coils on an integral stator core, a method of arranging coils on split cores formed by dividing the stator core, and connecting the split cores on which the coils are arranged. method etc. In addition, the coil may be formed by winding a plurality of gathered thin-diameter magnetic wires, or formed by winding a single flat wire. In the case of winding one flat wire to form a coil, Patent Documents 1 and 2 exist, for example, as techniques showing a method of attaching the coil to the teeth of the stator core. [0003] Patent Document 1 discloses an apparatus for manufacturing a motor stator in which a plurality of trapezoidal coils form...
