A novel mathematic model for a dual three-phase permanent magnet synchronous machine(pmsm) was proposed. A set of equivalent three-phase windings was built based on same magnetomotive force and power. Then it can substitute the old dual three-phase pmsm equivalently after a winding transformation...
High reliability is one of the primary advantages of the dual three-phase permanent magnet synchronous motor (DTP-PMSM). However, the single-phase open-circuit fault in the DTP-PMSM drive suffers from large current harmonics and significant torque ripple. To solve these problems, a fault-tolerant...
In this paper, a fault-tolerant control is proposed for dual three-phase permanent-magnet synchronous machine (PMSM) drives under open-phase faults. The object of the proposed fault-tolerant control is to maximize the torque capacity while the overcurrent protection is taken into account. Hence,...
Because of some factors such as air-gap magnetic field distortion and nonlinear characteristics of inverter, the stator winding of a dual three-phase permanent magnet synchronous motor (PMSM) usually contains a large amount of harmonic current. The harmonic current will increase system losses and cau...
