Problems solved by technology

[0003] However, since the switched reluctance motor rotor has no coil windings, the complexity of the switched reluctance motor generator is increased, that is, the stator winding is both an excitation winding and a power generation winding. When each phase winding is energized in turn, the motor will generate electromagnetic torque. , so that the motor rotates continuously, its power generation efficiency has certain limitations

Abstract

The present invention relates to a switch reluctance motor electricity generator, which comprises stator, rotor and driving device in salient pole structure pressure-superposed by silicon steel sheet, wherein tooth of the stator is provided with centralized armature winding; the armature winding are connected in series or in parallel to constitute a phase on two tooth of same windings phase, characterized in that the rotor is provided with windings. The driving device of the electricity generator can adopt either electronic sensor or mechanical driving device or combining both. The present invention breaks adding exciter winding on electric machine rotor in normal way, which enhances performance and efficiency of power generation.

Description

technical field [0001] The invention relates to the field of motors, in particular to a switched reluctance motor generator. Background technique [0002] The switched reluctance motor is a motor with a double salient pole structure. The salient poles of the stator and rotor are laminated with ordinary silicon steel sheets. The rotor has neither winding nor permanent magnet, and the stator pole is wound with a concentrated winding. The number can be divided into single-phase, two-phase, three-phase, four-phase and multi-phase switched reluctance motors, among which the three-phase 6 / 4 structure and the four-phase 8 / 6 structure are the majority. The switched reluctance motor has the advantages of simple structure, easy manufacture, reliable operation, not easy to damage, easy speed regulation, high power factor, high efficiency, large starting torque, small starting current, strong overload capacity, and can start with heavy loads. Its high-speed constant power range is wide...
