Abstract:
A rotating electrical machine includes a magnetic field-producing unit, an armature with a multi-phase armature winding, and a rotor. The magnetic field-producing unit includes a first portion and a second portion. The first portion is located closer to a d-axis in a d-q axis coordinate system than the second position is. The second position is located closer to a q-axis in the d-q axis coordinate system than the first position is. The magnetic field-producing unit is magnetically oriented to meet a condition where an angle which an easy axis of magnetization of the first portion makes with the d-axis is smaller than an angle which an easy axis of magnetization of the second portion makes with the q-axis. The magnetic field-producing unit is configured to have an intrinsic coercive force of 400 kA/m and also have a remanent flux density of 1.0 T or more.
