Abstract
A rotating electric machine is applied to a multilayer winding-type rotating electric machine including a stator and a rotor. The stator includes an armature winding. The rotor includes at least one of a field winding and a permanent magnet for generating a magnetic field that have characteristics of magnetic flux of a non-sinusoidal waveform in relation to a rotation angle of the rotor. The armature winding has winding groups. Each of the winding groups has coils that are connected to an actual neutral point provided for each winding group, and has a first winding group and a second winding group that have a phase difference. A control apparatus detects a rotation angle based on a voltage at the actual neutral point of the first winding group and a voltage at the actual neutral point of the second winding group, and controls the rotating electric machine based on the rotation angle.
