Stator current sharing will be unbalance in dual three-phase permanent-magnet synchronous motor (DTP-PMSM) drives since two three-phase systems have inherent asymmetries. In this paper, a simple current sharing scheme is proposed to eliminate the inherent asymmetries of the two three-phase systems. It will enable the motor to operate with balance current sharing between the two three-phase winding...
Multiphase motor drives have many advantages over the traditional three-phase motor drives. In this paper we firstly deduce the mathematic modeling for a dual-three-phase permanent magnet synchronous motor (PMSM) according to vector space decomposition theory. Then, a sensorless vector control based on the model reference adaptive system (MRAS) is developed for a dual-three-phase PMSM and the system...
