Description

technical field [0001] The invention relates to a three-phase single-stage double-pole switched reluctance motor, in particular to a three-phase single-stage and double-stage double-pole switched reluctance motor. Background technique [0002] At present, the switched reluctance motor is a double-salient switching motor, and its stator poles are wound with concentrated windings; the motor can be divided into single-phase, three-phase, and four-phase switched reluctance motors according to the number of phases, and the three-phase 6 / 4, 12 / 8, and four-phase 8 / 6 structures are the majority. Switched reluctance motors have simple structure, easy manufacturing, easy speed regulation, reliable operation, not easy to damage, high power factor, high operating efficiency, large starting torque, It has the advantages of small starting current, strong overload capacity, heavy load starting, etc., and has good performance in a wide range of high-speed constant power range.
