The paper examines the excitation of a variable-reluctance motor drive operating at constant speed. The excitation refers to a prescribed relationship between the phase currents and rotor position that results in the desired drive behavior. An analytical method for the determination of currents and torque of a motor including saturation effect is presented. The model includes all significant electromagnetic and dynamic characteristic of variable-reluctance motor. A piecewise analytical analytical formula for an instantaneous torque is also included, permitting the rapid calculation of mathematically smooth torque waveforms. Because the magnetization curves do not need to be precalculated, stored or curve-fitted, the algorithms are extremely fast.
