| 20080315705 | ROTATING ELECTRIC MACHINE, WINDING MACHINE, AND ROTATING ELECTRIC MACHINE SYSTEM - A rotating electric machine includes a stator core of a cylindrical shape, a rotor core coaxially rotating inside the stator core, and a plurality of coils each formed by winding magnet wires using a slot formed axially in either the stator core or the rotor core, or both: it is preferable that each of the coils be split into a plurality of coil groups, that starting sections of winding of the magnet wires in one of the coil groups be wound adjacently to ending sections of winding of the magnet wires in another of the coil groups, and that the starting sections and ending sections of winding of the magnet wires in the two coil groups be connected at respective outgoing wire ends to one another, outside the slots. | 12-25-2008 |
| 20080317620 | Rare earth element magnet - A rare earth element magnet comprising molded magnetic powder containing at least one rare earth element, wherein a Fe rich phase covering a part or entire of the surface of particles of the magnetic powder and having a Fe atomic percentage larger than that of the magnetic powder, and an inorganic binder bonding the particles covered with the Fe rich phase. | 12-25-2008 |
| 20100001609 | ROTATING ELECTRIC MACHINE - An object of the present invention is to provide a compact, high-power rotating electric machine by downsizing coil ends on a distributed-wound stator using rectangular wires in comparison with the conventional one or by enhancing coil heat radiation from the coil ends or slot insertion portions. | 01-07-2010 |
| 20100007232 | Sintered Magnet Motor - Disclosed herein is a sintered magnet motor having a sintered magnet rotor, the rotor comprising: a ferromagnetic material comprising iron as a main ingredient to be sintered; a fluorine compound or an oxyfluoride compound formed in the inside of a crystal grain or to a portion of a grain boundary of the ferromagnetic material; and at least one of alkalis, alkaline earth elements, and rare earth elements contained in the fluorine compound or the oxyfluoride compound; a portion of the fluorine compound or the oxyfluoride compound being distributed with a concentration gradient established from the surface to the inside of the ferromagnetic material, and a rare earth element being distributed with a concentration gradient established between the grain boundary surface and the parent phase of the ferromagnetic material, wherein the concentration distribution of the fluorine compound is asymmetrical when viewed from the pole center of the sintered magnet rotor. The amount of use of a fluorine compound can be decreased in this sintered magnet motor. | 01-14-2010 |
