Problems solved by technology

Therefore, it is necessary to attach a large component close to the stator core, which is likely to cause an increase in the size and weight of the device
[0010] In addition, in the above-mentioned conventional rotating electric machine, it is necessary to provide a complex shape of the connection portion for connecting the wires of each coil to the midpoint bus ring, so the manufacturing cost may also be increased.

Embodiment Construction

[0054] Hereinafter, a rotating electrical machine according to an embodiment of the present invention will be described based on the drawings.

[0055] figure 1 It is a figure which shows the stator 1 incorporated in the electric rotating machine of this embodiment. figure 2 It is a figure which shows the single body of the stator core 2 of the stator 1. image 3 It is a figure which shows the state which assembled the stator 1 and the terminal block 3 in the case 4.

[0056] The rotating electrical machine of this embodiment is a three-phase AC type rotating electrical machine used for vehicle drive and regenerative power generation of an electric vehicle or a hybrid vehicle, and a rotatable rotor (not shown) is disposed inside an annular stator 1 . . The rotor is coupled to an axle of the vehicle via a reduction mechanism or the like.

[0057] The stator 1 includes: an annular stator core 2 on which a plurality of coil wires 5 are attached in salient-pole concentrated w...

Abstract

A rotary electric machine includes: a stator core that is formed of a plurality of split core pieces that are annularly arranged therein, coil conductors being wound around respective split core pieces. One ends of the respective coil conductors which are wound around the respective split core pieces are connected to power supply terminals for corresponding phases, and other ends of the respective coil conductors are connected to each other to form a neutral point, the respective coil conductors are formed of rectangular wires, and the neutral point-side end portions of the respective coil conductors are led to an outside of the stator core from one point on a circumference of the stator core.

Description

technical field [0001] The present invention relates to a rotating electrical machine used for driving a vehicle or regenerative power generation, and more particularly to a rotating electrical machine in which a plurality of coil wires are wound around an annular stator core. [0002] this application claims priority based on Japanese Patent Application No. 2011-255217 for which it applied to Japan on November 22, 2011, and uses the content here. Background technique [0003] In a rotating electric machine used for vehicle driving or regenerative power generation, in order to facilitate the winding operation of the coil wire and improve the space factor, there is known a technique in which the stator core is composed of a plurality of divided coil pieces (for example, refer to Patent No. Literature 1). [0004] Patent Document 1 discloses a rotating electrical machine in which a coil wire is wound on each split core piece, the split core pieces around which the coil wire i...
