Title:
PERMANENT MAGNETIC BIAS MAGNETIC TYPE RELUCTANCE MOTOR
Document Type and Number:
WIPO Patent Application WO/2004/091071
Kind Code:
A1
Abstract:
This invention belongs to electric machine field, particularly relates to the advances of reluctance motor or reaction motor, that is a permanent magnetic bias magnetic type reluctance motor. It includes housing, stator, rotor and permanent magnet, and the stator core is at least composed of a pair of soft magnetic material which has wire groove, magnetic yoke and furcate finger, the furcate fingers of conjugated stator cores are arranged interlaced with a permanet magnet between them. A wire groove is arranged on adjacent furcate fingers of the stator core, and there are also has wire grooves on the furcate fingers. This invention is bias magnetic by using permanent magnet, because it has advantage which are saving copper wire more than half of them and locating wire space, predigest external wires, reducing motor size, reducing copper loss and iron loss, increasing efficiency. In addition, the connection of drive circuit can be agiler.
