一种抑制无刷直流电机转矩脉动且最小化转子涡流损耗的新型电流方案

In this paper, a novel current solution is proposed to suppress the electromagnetic torque ripple of brushless dc motor (BLDCM), and simultaneously minimize the rotor eddy-current loss to prevent thermal demagnetization of the permanent magnets. To determine the current solution, an optimizing problem of the rotor loss is developed, subjecting to the constraints of average torque and the sixth har...
