    摘要： The stator winding includes: a first three-phase wye-delta hybrid winding that is configured by connecting phase windings of a first wye winding to respective output ends of a first delta winding; and a second three-phase wye-delta hybrid winding that is configured by connecting phase windings of a second wye winding to respective output ends of a second delta winding. The phase windings of the first and second wye windings are configured by connecting two winding portions in parallel, and those two winding portions are configured such that distributions of radial positions inside slots of conductor wires that constitute the winding portions are equal.

    摘要： The present invention provides a dynamoelectric machine that enables heat that is generated in a permanent magnet to be transmitted to a fan and be radiated from the fan effectively, that suppresses occurrences of damage to the fan that result from centrifugal forces that act on the permanent magnet, and that also enables the fan to be prepared easily and inexpensively.In a dynamoelectric machine according to the present invention, a magnet holder (30, 35) that is made of a magnetic material is disposed so as to span over a trough portion (26, 27), an interfitting groove (31, 36) that has a groove direction in an axial direction is formed on the magnet holder (30, 35) so as to open radially outward, and so as to lead inward from an axially outer side, and a permanent magnet (32, 37) is held by the magnet holder (30, 35) by being fitted into the interfitting groove (31, 36) and is disposed so as to face an inner circumferential surface near a tip end of claw-shaped magnetic pole portions (24, 20) and have a predetermined clearance. In addition, a metal fan (40A, 40B) is fixed to an end surface of a pole core body (17, 21), a thermally conductive plate (43) is disposed so as to extend from a base portion (41) axially inward, and a leading end portion thereof is press-fitted between a lower surface of the permanent magnet (32, 37) and a bottom surface of the interfitting groove (31, 36).
