Provided are multiple switched reluctance motors and excitation control methods for same. Motors with various structures are provided having the same structural characteristics, to wit, a stator formed of an even number of salient pole pairs (101, 102) and a rotor formed of an even number of salient pole pairs (104, 105). The salient poles of the stator salient pole pairs (101, 102) are arranged opposite the salient poles of the rotor salient pole pairs (104, 105), with minimal air gaps left between said salient pole pairs, thus leaving the shortest magnetic return paths between the stator salient pole pairs (101, 102) and the rotor salient pole pairs (104, 105) arranged opposite one another, thus satisfying the minimum reluctance principle of the switched reluctance motor. In addition, due to the magnetic isolation between each stator salient pole pair, the performance of the magnetic pole of each stator salient pole pair (101, 102) is controlled by an excitation control power source and changed independently. Also provided are novel excitation control methods for motors having the described structural characteristics. Each stator salient pole pair (101, 102) of the motors can participate to the maximum in exerting effect on the rotor salient pole pair (104, 105), thus allowing the motors to obtain greater continuous torque and higher power density. |
