Abstract :
A method to predict the torque-speed characteristics of a bifilar hybrid step motor with an inverse-diode-clamp drive circuit is presented. The phase energization control strategies that maximize and minimize average torque production are found. A closed-form expression for average torque produced by the motor is found by representing the flux linkages and model parameters as Fourier series
