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.

[ What is claimed is:] [1.]1. A reluctance type rotating machine comprising:a stator having armature windings;a rotor having a rotor core, the rotor being provided, in a circumferential direction thereof, with a magnetic unevenness;a plurality of permanent magnets arranged in the rotor core, each of the permanent magnets having a magnetization direction and the magnetization directions of selected of said magnets being arranged in a direction opposite the direction of magnetization of magnets adjacent the selected magnets to produce alternating magnetic poles and magnetic interpoles and provide said magnetic unevenness;wherein an armature current flux in a radial direction of the rotor at the magnetic interpoles between the magnetic poles and the flux of the permanent magnets negate each other, so that the composite interlinkage flux in the radial direction of the rotor at the magnetic interpoles between the magnetic poles is substantially equal to zero.
