ABSTRACT:
In a switched reluctance motor and control system for such a motor, a rotor comprises four salient poles each having a width of about 50-degrees, and a stator has six salient poles each having a width of about 30-degrees. One Excitation winding is mounted around each stator salient pole and these are connected in series. An excitation drive circuit supplies a dc excitation current to each excitation winding to excite the motor in accordance with an excitation command signal. A torque-current drive circuit renders a current, whose magnitude in accordance with a torque command, to flow into torque windings mounted one round on each of the six stator salient poles successively according to the angle of rotation of the rotor.
