    摘要： The present invention provides a compact electric motor, thus ensuring improved in-vehicle mountability. A pump is driven by an electric motor. The pump has a coil 14 disposed 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 end of the other member thereof. The electric motor drives the pump by rotating a rotor 16 disposed to face the inner periphery 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 the 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： It is made easy for a stator winding to be wound around a stator core and degradation in efficiency is prevented as much as possible. A stator (6) includes a plurality of phases, i.e., of circumferentially divided stator magnetic poles (6a, 6b, 6c). The stator magnetic poles (6a, 6b, 6c) are each composed of an arcuate stator core (13) having a plurality of axially extending claw poles (16b) and a circumferentially elliptically wound stator winding (14). The stator magnetic poles (6a, 6b, 6c) are magnetically divided; therefore, magnetic flux leakage is reduced to improve efficiency. Air flowing between the stator magnetic poles (6a, 6b, 6c) can improve a cooling effect.
