Switched reluctance motor is one of the most recently developed electrical motors which is
characterized by its simplicity, ruggedness and flexibility of its operating characteristics. In spite
ofthese it suffers from torque pulsations and the lack of a standard power electronic converter due
to its uni-polar current excitation pulses. This paper introduces an alternative variable reluctance
motor with filly-pitched winding and bipolar excitation which can be supplied by a standard
power electronic switch module and has a ripple-free torque. Throughout the present work a
mathematical model for the proposed motor type is developed and investigated by computer
simulation. The operating characteristics for this type are presented along with those of the
conventional switched reluctance motor, which emphasis the better performance ofthe proposed
motor type.
