Title:
RELUCTANCE MOTOR
Document Type and Number:
WIPO Patent Application WO/1997/005692
Kind Code:
A1
Abstract:
A reluctance motor comprising a fixed armature (1) and a rotor (5) of a magnetic substance disposed inside the armature (1) with a gap between them. Two salient poles (5a, 5b) having a width which is 2.5 times the angular pitch of slots (1a, 1b, ..., 1h) of the armature (1) are disposed round the outer peripheral portion of the rotor (5). A magnetic flux due to the excitation of armature coils (2h, 2d) of magnetic poles (4h, 4d) situated at positions at which no torque is generated is combined with the magnetic flux due to the excitation of armature coils (2a, 2e) of magnetic poles (4a, 4e) situated at positions in a direction of an arrow R at which a torque is generated. As a result, leakage fluxes Fa and Fb between the magnetic poles (4a, 4e) and the salient poles (5a, 5b) of the rotor (5) increase and the torque can be increased.
