摘要： 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.

摘要： A power conversion system, including a converter for converting an AC power from a power source to a DC power, a DC capacitor for smoothing the DC power output from the converter, an inverter for converting the DC power smoothed by the DC capacitor to an AC power of an arbitrary frequency to drive and control an induction motor, a unit for detecting or computing a magnetic flux axis of the induction motor, a unit for computing a current orthogonal to the detected or computed magnetic flux axis, and a phase control unit for controlling a phase angle of an output voltage of the inverter so that a value of the current orthogonal to the detected or computed magnetic flux axis is maintained at a constant level.
