摘要 |
In the present invention, at a time of a heating high-load operation, a harmonic current is flown in an armature winding (16CR) to induction-heat rare-earth magnets (14MRb), thus reducing a residual magnetic flux density. Thereby, the number of rotations of a radial gap type motor (10R) is improved. The rare-earth magnets (14MRb) are provided near a cooling medium passage (30P) extending substantially in parallel with a flow line of a cooling medium, so that the cooling medium recovers heat of the heated rare-earth magnets (14MRb). At a time of a cooling high-load operation, a greater number of rotations are obtained with respect to the same torque command value, by a field weakening control by means of a current-phase advance. |
