Abstract

An electric rotating machine comprising a first three-phase Y- mixed winding and a second Y- mixed winding wound around a stator core having a plurality slots. A first -U winding section and a first Y-U winding section are contained in the same slot, a first -V winding section and a first Y-V winding section are contained in the same slot, and a first -W winding section and a first Y-W winding section are contained in the same slot. A second -U winding section and a second Y-U winding section are contained in the same slot, a second -V winding section and a second Y-V winding section are contained in the same slot, and a second -W winding section and a second Y-W winding section are contained in the same slot.

Description

(1) Technical field [0001] The present invention relates to, for example, a rotating electrical machine driven by an internal combustion engine and mounted on cars, trucks, and the like. (2) Background technology [0002] In recent years, in vehicle alternators, it is necessary to increase the power generation output as the vehicle load increases. As a device for realizing the increase in power generation output, for example, Japanese Patent Laid-Open No. 5-308751 discloses a device with 2 A vehicle alternator with independent 3-phase stator windings. [0003] However, in this device, since the two sets of stators are arranged in the axial direction of the shaft, the dimension in the axial direction increases, and there is a problem of an overall increase in size. (3) Contents of the invention [0004] In order to solve the above-mentioned problems, an object of the present invention is to provide a rotating electrical machine capable of achieving a small size while ensur...
