Abstract:
A rotating electric machine includes a field system having a magnet section and an armature having a multi-phase armature coil. The magnet section has easy axes of magnetization oriented to be more parallel to a d-axis at locations closer to the d-axis than at locations closer to a q-axis. The magnet section has an intrinsic coercive force higher than or equal to 400 [kA/m] and a residual flux density higher than or equal to 1.0 [T]. There are no inter-conductor members provided between electrical conductor sections of the armature coil. The armature coil includes a plurality of phase windings each of which is constituted of a plurality of partial windings. Each of the partial windings is formed of an electrical conductor that is multiply wound in the electrical conductor sections of the same phase. In each of the phase windings, the partial windings are connected in parallel with each other.
