  • Reluctance motor system, driving circuit, and reluctance motor
    Patent number: 9425657
    Abstract: A reluctance motor system includes a reluctance motor having a stator and a rotor, and a driving circuit. The stator includes phase winding sets each of which includes two windings that are connected in series at a corresponding node. The driving circuit includes switching members each of which is coupled electrically to a respective phase winding set, and each of which includes a first switch, a second switch, a first flyback diode, and a second flyback diode. The driving circuit further includes damping capacitor sets each of which includes a first capacitor coupled between the node and a positive terminal of a DC power source, and a second capacitor coupled between the node and a negative terminal of the DC power source.
    Type: Grant
