摘要： The present invention provides a compact electric motor, thus ensuring improved in-vehicle mountability. A pump is driven by all motor. The pump has a coil 14 deposed in a ring form around and along a stator core 13. The stator core 13 has a plurality of claw magnetic poles which extend alternately from both ends of one member of the stator core 13 toward the of the other member thereof. The electric motor drives the pump by rotating a rotor 16 disposed to face the inner of the stator core 13 as the coil 14 is energized. The present invention provides a compact electric pump with no coil ends, thus ensuring improved in-vehicle mountability. Further, the present invention permits efficient cooling of the electric motor adapted to discharge a cooling medium. Still further, the present invention permits use of a stator core made from a compressed powder core by molding with resin. In addition, the molded portion also serves as a partition separating pump and motor units.

摘要： The present invention comprises a stator, and a rotor which is disposed oppositely to the stator with a gap interposed. The stator comprises a stator core, and a distributed stator winding mounted to the stator core. The stator core comprises a ring-like yoke core, and a plurality of teeth cores which protrude from the yoke core in the radial direction. The rotor comprises a rotor core, and a plurality of permanent magnets embedded in the rotor core. A pair of non-magnetic portions is created inside the rotor core and on both sides of the circumferential width of a permanent magnet for one magnetic pole. In the rotor core located on the stator side of the pair of non-magnetic portions, a pair of magnetic paths is created as the result of the creation of the pair of non-magnetic portions. Furthermore, a groove or hole is created on the outer circumferential portion of the rotor core and between the adjacent magnetic poles.
