“…By this structure, if an open-circuit fault happens on one of the phase windings, the average torque developed by the R-FSPM can be preserved by increasing the current in the healthy windings [42]. Additionally, by utilizing the harmonic current injection method [43], the needed current can be reduced with no average torque reduction or severe torque ripple. The straight forward approach to make a motor tolerant to a phase fault is to maintain it operation by the help of the remaining healthy phases.…”

Abstract:The paper presents a number of advanced solutions on electric machines and machine-based systems for the powertrain of electric vehicles (EVs). Two types of systems are considered, namely the drive systems designated to the EV propulsion and the power split devices utilized in the popular series-parallel hybrid electric vehicle architecture. After reviewing the main requirements for the electric drive systems, the paper illustrates advanced electric machine topologies, including a stator permanent magnet (stator-PM) motor, a hybrid-excitation motor, a flux memory motor and a redundant motor structure. Then, it illustrates advanced electric drive systems, such as the magnetic-geared in-wheel drive and the integrated starter generator (ISG). Finally, three machine-based implementations of the power split devices are expounded, built up around the dual-rotor PM machine, the dual-stator PM brushless machine and the magnetic-geared dual-rotor machine. As a conclusion, the development trends in the field of electric machines and machine-based systems for EVs are summarized.

“…However, the implement suffers from high cost because the PMs or the windings should be placed on the long stator. In order to overcome this shortcoming, a new class of PM motors, whose PMs and windings are located in the same side of the motor, have attracted wide attention [7][8][9][10][11][12], such as doubly salient PM motors, flux reversal PM motors, vernier PM motors, and flux-switching PM motor. Among these PM machines, the vernier PM motor has significant advantage of high torque/ force capability due to its special magnetic gear flux field modulation [13][14][15].…”

-A linear permanent-magnet vernier (LPMV) motor has magnets and windings in the short mover, which is very suitable for long stroke applications. This paper proposed a new field oriented control with space vector pulse width modulation for the LPMV motor, which considers loss minimization. First, the topology of the LPMV motor is briefly presented. Then, the mathematical model is derived, and the mover field oriented control strategy is proposed. Also, the loss analysis is performed. Finally, the simulated and experimental results are given, verifying the feasibility and effectiveness of the proposed control strategy.

“…In order to generate optimal current references in fault mode, a vector approach was reported in [21], which requires relatively simple computations. The authors of [22] adopted a new control strategy for fault-tolerant operation of the redundant flux-switching PM machine drive by injecting the harmonic currents, in which the capability limitation of the power converter is considered. A generalized optimal fault-tolerant control technique was proposed in [23,24] for a five-phase PM machine drives with open-circuit fault.…”

Abstract:A fault-tolerant permanent-magnet vernier (FT-PMV) machine incorporates the merits of high fault-tolerant capability and high torque density. In this paper, a new remedial control is proposed for a five-phase FT-PMV machine with short-circuit fault of stator windings. Based on the principle of copper loss minimization, the aims of the proposed control strategy are to keep magnetic motive force (MMF) unchanged and minimize torque ripple. The proposed remedial control strategy contains two parts. Firstly, the remedial currents of the healthy phases are used to compensate for the ripple of MMF caused by the short-circuit current. Secondly, an open-circuit fault-tolerant control strategy is used to compensate for the lack of normal torque in the fault phase. Finally, the vector sum of two parts is adopted to derive the remedial currents. The final expression of the proposed remedial current is simpler than that than these previous methods. In addition, the proposed remedial currents are sinusoidal, which can reduce the reactive component in instantaneous power produced by pulsating torque and iron loss of a sine back-EMF machine. A FT-PMV prototype is built. The simulations and the experiments verify the effectiveness of the proposed strategy.
