Problems solved by technology

In addition, due to this inductance loss, the control content of the salient pole motor becomes complicated.
[0007] In the three-phase motor of the above-mentioned prior art, since windings for each of the three phases are required, it is difficult to suppress the increase in the number of parts required for the structure of the stator, and there is a problem of winding the windings for eac

no. 1 approach

[0194] Hereinafter, a first embodiment of the stator of the present invention will be described with reference to the drawings.

[0195] The stator 10 of this embodiment constitutes, for example, a salient-pole motor mounted on a hybrid vehicle as a drive source of the vehicle together with an internal combustion engine, and is configured, for example, in a structure in which the internal combustion engine, the salient-pole motor, and a transmission are directly connected in series. In a parallel hybrid vehicle, at least the driving force of either the internal combustion engine or the salient-pole motor is transmitted to the drive wheels of the vehicle through a transmission.

[0196] Also, when the driving force is transmitted from the driving wheel side to the salient pole motor when the vehicle decelerates, the salient pole motor functions as a generator to generate so-called regenerative braking force, and recovers the kinetic energy of the vehicle body as electric energy ...

no. 2 approach

[0228] Hereinafter, a second embodiment of the stator of the present invention will be described with reference to the drawings.

[0229] As in Embodiment 1, the stator 110 of this embodiment constitutes, for example, a salient-pole motor mounted on a hybrid vehicle as a driving source of the vehicle together with an internal combustion engine. For example, the internal combustion engine, the salient-pole motor, and the transmission In a parallel hybrid vehicle having a structure in which the devices are directly coupled, at least the driving force of either the internal combustion engine or the salient pole motor is transmitted to the driving wheels of the vehicle through the transmission.

[0230] When the driving force is transmitted from the drive wheel side to the salient pole motor when the vehicle decelerates, the salient pole motor functions as a generator to generate so-called regenerative braking force, and recovers the kinetic energy of the vehicle body as electric e...

no. 3 approach

[0306] Hereinafter, a third embodiment of the stator of the present invention will be described with reference to the drawings.

[0307] The stator 50 of the third embodiment differs from the stator 110 of the above-mentioned second embodiment in that the U-phase loop winding 54 and the W-phase loop winding 55 do not have the respective U-phase meandering parts 131 and W-phase meandering parts 131 . Section 132 of this.

[0308] Hereinafter, the description of the same parts as those of the second embodiment will be simplified or omitted.

[0309] For example Figure 24 and Figure 25 As shown, the stator 50 of this embodiment includes: a U-phase stator ring 51, a V-phase stator ring 52, a W-phase stator ring 53, and a U-phase stator ring 53 for each of the three phases composed of a U-phase, a V-phase, and a W-phase. Two-phase U-phase toroidal winding 54 and W-phase toroidal winding 55 constituted by a phase and a W-phase.

[0310] The U-phase stator ring 51 has a substan...

Abstract

The invention provides a method, which overlay connects axially track rings (11), (12), (13) in order, to make the rings has the same axis with a shaft line (P). Arranging axially each claw-like induced poles (22), (24), (26). When the axial end-face of A phase rear yoke (21) contacts with the other axial end-face of B phase rear yoke (23), the base ends of claw-like induced poles (22), (24) arranged along the axis with proper interval, axially grip alpha phase ring winding (14) and fixed the winding. When the other axial end-face of B phase rear yoke (23) contacts with the axial end-face of D phase rear yoke (25), the base ends of claw-like induced poles (242), (26) arranged along the axis with proper interval, axially grip beta phase ring winding (15) and fixed the winding.

Description

technical field [0001] The invention relates to a stator, a motor and a method for manufacturing the stator. [0002] This application is for: Japanese Patent Application No. 2005-055670 filed on March 1, 2005, Japanese Patent Application No. 2005-055671, Japanese Patent Application No. 2005-055672, Japan filed on March 2, 2005 Priority of Patent Application No. 2005-057141, Japanese Patent Application No. 2005-057142, Japanese Patent Application No. 2005-306778 filed on October 21, 2005, and Japanese Patent Application No. 2005-306780, incorporated herein by reference its content. Background technique [0003] Conventionally, as a conventional salient pole motor, it is known that, for example, three-phase stator rings composed of U phase, V phase, and W phase are arranged so as to be superimposed coaxially along the axial direction. On the ring-shaped winding installation part formed between adjacent stator rings, the ring-shaped windings that generate the rotating magnet...
