“…In this work, since the machine is working as a generator and the input torque from the prime mover stays constant, then the effect of the speed control through FOC is creating a higher risk for the machine. This is fundamentally different than a previous work published by one of the authors in [32] where the 3-phase short-circuit was studied without FOC and at constant input speed.…”

To assess demagnetization, a line-to-line short-circuit fault study is carried out with constant input torque and field-oriented control (FOC) for the speed of a permanent magnet synchronous generator (PMSG). For the study, a cosimulation between finite element analysis (FEA), power electronics simulation (Simplorer) and model-based control design software (Matlab Simulink) is used. The analyzed system was previously validated in the experimental set-up with DS1103 card. The initial short circuit currents, although higher than nominal, did not present a risk of demagnetization for the generator in the analyzed working conditions, namely magnets temperature and speed. Nevertheless, the acceleration during the fault, due to constant input torque, and the control scheme with a constant speed reference, provided a greater demagnetizing current while breaking the machine speed back to the pre-fault reference. The cosimulation results bring higher fidelity to the modeling and analysis of the behavior of the PMSG under FOC.

“…Consequent pole machines do not reduce the overall PM material in a machine, even if the number of magnets is reduced. Each magnetized pole still has to be dimensioned for the complete pole pair including the iron poles [122,123]. The iron of poles without PMs can be used as an advantage in hybrid excitation.…”

Hybrid excitation is a technology that combines the advantages of field windings and permanent magnets for inducing magnetic flux. This article studies the benefits of hybrid excitation and provides an outlook on their possible applications, such as wind power generators and electric vehicle motors. Compared to permanent magnet-based machines, hybrid excitation gives a variable flux while still using the advantage of the permanent magnets for a portion of the flux. This article also looks into some different categories of machines developed for hybrid excitation. The categories are based on the reluctance circuit, the relative geometrical location of the field windings relative to the permanent magnets, or the placement of the excitation system.

“…For the drive motor used in EV drive systems, it is necessary to meet the requirements of a large torque output in the lowspeed area and a wide constant-power speed range in the high-speed area. However, the permanent-magnet magnetic field is difficult to adjust, which limits the application of PMSM in situations involving wide constant-power speed range requirements [5][6][7][8][9][10].…”

Optimization Design and Performance Analysis of a Reverse-Salient Permanent Magnet Synchronous Motor

The reverse-salient permanent magnet synchronous motor (RSPMSM) is a competitive candidate for electric vehicles due to its high torque density and high efficiency. This paper proposes an optimized RSPMSM by adopting a segmented permanent magnet structure. First, the structure, electromagnetic torque, and current control laws of the RSPMSM are introduced in detail. Second, the optimization design method of the RSPMSM is proposed by taking the torque and constant-power speed range as optimized objectives, with the saliency ratio as a constraint. The optimized model of the RSPMSM is determined using the genetic algorithm (GA). Further performance analysis and comparisons are made between the initial motor and the optimized motor. Finally, a prototype is manufactured, and the performance of the RSPMSM is verified through the finite element method (FEM) and experiments.
