Abstract
A rotating electrical machine includes a magnetic field-producing unit equipped with a magnet unit including a plurality of magnetic poles, and an armature which includes a multi-phase armature winding. The armature winding has conductor portions which are arranged at a given interval away from each other in a circumferential direction. The armature is designed to have conductor-to-conductor members arranged between the conductor portions in the circumferential direction. The armature may alternatively be designed not to have the conductor-to-conductor members disposed between the conductor portions in the circumferential direction. The magnet unit is magnetically oriented to have an easy axis of magnetization which is directed in a region close to a d-axis that is a center of a magnetic pole to be more parallel to the d-axis than that in a region close to a q-axis that is a boundary between magnetic poles.
