Abstract: A connection member for supplying a stator winding with a current is constituted by covering a bus bar with a insulating resin. The bus bar is formed in an arc-like shape in the thickness direction of a belt-shaped conductor. Additionally, a weld zone formed on the bus bar has a projection portion projecting in the width direction, a first bent portion bent outside the arc from the projection portion in the thickness direction, and a second bent portion with the tip end thereof folded back in the width direction to allow the tip end of the second bent portion to be welded to a terminal on the stator winding.

Abstract: An insulator includes: a trunk portion that is interposed between a tooth and a stator coil; and a first flange portion that is disposed on the trunk portion so as to be adjacent to the stator coil in a radial direction of a stator core. A notch portion is disposed on a flange protruding portion of the first flange portion that protrudes from the stator core in the axial direction of the stator core from an outer circumferential portion of the flange protruding portion toward the trunk portion. A holder that has a holder main body that is disposed on the notch portion is mounted onto the flange protruding portion. A temperature sensor is held between the holder main body and the stator coil.

Abstract: A fixing member (14) formed of an annular metal material is molded integrally with a connecting plate (13) to constitute a connecting plate structure (9), said connecting plate (13) consisting of a plurality of bus bars (11) and a holder (12) for fixing and holding the bus bars. The fixing member (14) has an annular portion (14a) touching a frame (8) for holding a stator (4), and the connecting plate structure (9) is fixed to the frame (8) by the whole or a part of the surface of the annular portion.
