A reluctance type rotating machine includes a stator 1 having armature windings 2 arranged on an inner periphery of the stator 1, a rotor 3 having a magnetic unevenness in the circumferential direction and a plurality of permanent magnets 6 arranged for negating the armature windings' flux passing between adjoining poles. Each magnet 6 is magnetized in a direction different from a direction to facilitate the rotor's magnetization. A magnetic portion 7 is provided between the pole and the interpole of the rotor 3. Owing to the provision of the magnetic portion 7, when the armature windings are not excited, more than 30% of the permanent magnets' flux is distributed in the rotor 3 Similarly, when the machine is loaded, the permanent magnets' interlinkage flux is more than 10% of composite interlinkage flux composed of armature current and the permanent magnets.

1. A reluctance type rotating machine comprising:a stator having armature windings; and a rotor surrounded by the stator and formed to generate inequalities in magnetism in a circumference of the rotor, said rotor including: a rotor core in which poles and interpoles are alternatively defined in a circumferential direction of the rotor; and a plurality of permanent magnets arranged in the rotor core along a radial direction of the rotor, and configured to negate an armature flux passing through the interpoles, wherein each of the interpoles has an outer face recessed in comparison with respective outer faces of the poles in the radial direction of the rotor.
