20100133961 | CONTROLLER-INTEGRATED ROTATING ELECTRICAL MACHINE - A controller-integrated rotating electrical machine includes a rotating electrical machine main body having a stator winding and a field winding and provided with a rotation detector that detects a rotation angle of a rotation shaft, a power circuit that controls a current flowing into the stator winding according to a detection output of the rotation detection portion, a field switching circuit that controls a current to flow into the field winding, and a capacitor connected in parallel with the power circuit and the field switching circuit. Both ends of the capacitor portion are connected to an external battery. The capacitor is disposed in closer proximity to the field switching circuit than the rotation detector, and connected to the field switching circuit via a common connection terminal. Noises superimposed on the rotation detection portion are thus reduced. | 06-03-2010 |

20140035431 | ROTATING ELECTRICAL MACHINE - To obtain a rotating electrical machine preventing a functional failure and shortening of the life of brushes caused by a temperature rise of the brushes installed to a vehicle AC power generator or a motor generator. A brush holder holding brushes supplying a field current to a rotor is provided with brush temperature suppressing metal members installed substantially parallel to the brushes in the vicinity of abutment portions of the brushes and slip rings in point-, line-, or surface-contact with the brushes at least at one point besides energization terminals. The brush temperature suppressing metal members not only diffuse heat generated at the brushes, but also function as a heat capacity for a case where a large amount of heat is generated in a short time, such as during regenerative power generation and a start-up operation, and thereby prevent an excessive temperature rise of the brushes. | 02-06-2014 |
