Title:
A MAGNETIC BIASHING RELUCTANCE MOTOR WITH EVEN POLES ON WHICH COILS ARE CONNECTED IN OPPOSITE DIRECTIONS
Document Type and Number:
WIPO Patent Application WO/2004/086593
Kind Code:
A1
Abstract:
The present invention relates to a kind of magnetic biashing reluctance motor with even poles on which coils are connected in opposite directions, comprising a housing, a stator and a rotor, characterized in that the stator is provided with drive coil and bias coil, the number of the poles for each phase of the stator is even number, the coils of the even poles are connected in series, half of the drive coil or bias coil are connected in opposite directions, the rest are connected in same direction. In the present invention, the direct bias is introduced, the drive coil and bias coil jointly use magnetic path so as to counteract the influence and interfere from each other, and by connecting with external circuit, a special bias current is supplied to bias coil, that is beneficial for drive coil to product fundamental wave, to restrain from producting higher harmonic wave, to improve the performance of motor. In the present invention, by providing the bias coil and the drive coil in the stator, the bias current is separated to excitate alone, so that the drive current is reduced, construction is simplified, performance of motor resembles that of synchronous machine, and the motor can four-quadrant-run.
