Torque control of the doubly‐salient reluctance motor

This paper describes an open‐loop torque control for a doubly‐salient reluctance motor. The reluctance motor is excited with current waveforms stored in a table. It is read out dependent on the reference torque, the speed and the rotor position of the drive. The currents were calculated off‐line, so that torque with little ripple is generated. The calculation is based on the interrelationship between the magnetic flux linkage, the phase current and the rotor position. A method for the measurement of this relationship is presented and the calculation of the phase currents are explained.
