ROTATING ELECTRIC MACHINE

Abstract

The invention relates to a rotating electric machine comprising a stator and a rotor. On the stator's iron core, the ends of the teeth define the openings of the slots through which the armature windings of different phases conduct, having two beveled edges at the two ends of the inner circumferential face, which are partially circumferentially removed. The rotor's iron core has grooves whose outer circumferential faces are concave along the central axis. Each groove produces a waveform in which the concave parts are located on either side of the convex part in the direction of rotor rotation, and the first groove is located on the leading side in the direction of rotation and the second groove is located on the rear side in the direction of rotation. The first and second grooves are asymmetrical with respect to the axis d.
