Title:
RELUCTANCE MOTOR AND ROTOR OF HIGH-SPEED RELUCTANCE MOTOR
Document Type and Number:
WIPO Patent Application WO/1993/015550
Kind Code:
A1
Abstract:
A reluctance motor, which has a small diameter, a high rotating speed and a high efficiency, or which has a large output torque, little vibration and, if necessary, which can be regeneratively braked. The rotor of the reluctance motor is made of a magnetic material and has two salient poles. In the stator of the reluctance motor, eight slots are provided at regular pitches, and through these slots wound are respectively first phase-fourth phase armature coils through which two-phase full wave currents flow. Thereby, both the size and diameter of the reluctance motor are small. Using the signal for sensing the rotational position of the rotor, the current having the width of 90° in electrical angle is applied to the armature coil, and thereby, the efficiency of the reluctance motor is made high at its maximum torque. Using as a medium the electrostatic energy of a capacitor having a small capacitance, the magnetic energy between two of the armature coils is converted in the shortest time, and thereby the reluctance motor can be rotated at a high speed.
