A Double Current Excitation Control Method for Suppressing Torque Ripple of the Novel SRM

In this paper, a double current excitation control method (DEC) is proposed to suppress the torque ripple of the novel SRM. The trough value of torque is increased by the overlapped two-phase armature current during commutation, while the peak value of torque is reduced by the inversely excited auxiliary excitation coil current, the smooth output of the motor torque is realized by the synergistic ...
