no. 1 Embodiment approach

[0045] exist figure 1 and figure 2 Among them, the rotating electric machine 1 according to the first embodiment of the present invention is constituted as a two-rotor type rotating electric machine, and includes: a stator 100 formed in a cylindrical shape; An outer rotating shaft (also simply referred to as a rotating shaft) 210 coincident with the rotating shaft 1C is fixed; and an inner rotor (first rotor) 300 is housed in the outer rotor (second rotor) 200, and is freely rotatable and fixed. There is an inner rotation axis (also simply referred to as rotation axis) 310 that coincides with the rotation axis 1C. The outer rotor 200 and the inner rotor 300 are respectively supported so as to be relatively rotatable around the rotation axis 1C. also, figure 1 A radial cross-sectional view of 180 degrees (1 / 2) out of 360 degrees of mechanical angle is shown. The inner rotor 300 constitutes a rotor in the present invention.

Abstract

The invention provides a rotating motor capable of smoothing torque ripple. The rotating motor (1) includes a stator (100) having an armature coil (104) for generating a magnetic flux by energization; an inner rotor (300) rotated by passage of the magnetic flux; and an outer rotor (200) disposed in a midway of a magnetic circuit passing through the magnetic flux of the inner rotor (300) and rotating. In the inner rotor (300), a plurality of rotor teeth (302) in which rotor windings (330) are winded are arranged in the circumferential direction in parallel. The rotor winding (330) is formed in integrated winding. The adjacent rotor windings (330) in the circumferential direction are opposite. The inner rotor (300) has a rectifying circuit in which the rotor windings (330) having the same current phase of an induced electromotive force are connected to a diode in serial.

Description

technical field [0001] The invention relates to a rotating electrical machine having a winding in the rotor. Background technique [0002] A rotating electric machine is mounted in various devices as a power source, and for example, it is mounted alone in a vehicle to function as a power source for an electric vehicle, or mounted together with an internal combustion engine to function as a power source for a hybrid vehicle. [0003] Especially in the case of a hybrid vehicle, it may be incorporated into a system that utilizes a combination of a planetary gear and an internal combustion engine for power generation and drive. In this case, there is a problem that the internal combustion engine, the electric generator for power generation, and the electric motor for driving are assembled into the system together with the planetary gears, which increases the size of the system, making it difficult to mount the system on a small vehicle. [0004] On the other hand, in the rotati...
