“…While hybridising wound machine features into PM machine, some benefits could be damaged, such as, simple mechanical structure and robust rotor, high power and torque density, and its low-loss excitation system [19]. The most promising benefit of excitation system hybridisation, therefore, is a wide CPSR in motoring mode, and proper control on the output voltage in generation mode [22,23], plus unity power factor capability, loss minimisation, and fault tolerance [7,24]. HR in excitation system is a design variable of HESM between one and zero.…”

For electric vehicles (EVs) with severe acceleration requirement, the selected motor would be inevitably overdesigned to meet the acceleration requirement. To address this, the motor constant power speed ratio (CPSR) should be increased to remove part of the overdesign. There are different flux weakening techniques that are used to increase motor maximum speed (and increase the CPSR). Among them, hybrid excitation synchronous motor (HESM) advantages have been benefited in this study. CPSR depends on hybridisation ratio (HR) of the excitation system, and the motor inductance. The relation is analytically derived in this study. In addition to increasing CPSR, HR can control the place of motor high-efficient area over the efficiency map, which can increase EV total efficiency. A search algorithm has been developed, here, to find the optimal HR of a nonoptimal HESM. The final design gives an efficient motor performance with less overdesign in drivetrain. Compared with the original permanent magnet synchronous motor, 4.1% improvement in total efficiency for an average city-highway driving cycle has been achieved, and 16% decrease in rated values of drivetrain elements is obtained.

This paper presents a finite simulation model of the hybrid excitation synchronous machine taking into consideration the saturation effect, the iron losses and including higher-order electromagnetic force harmonics. Simulation and experimental testing prove that the advanced model represents more accurately the machine especially when compared with the basic Park model built with sinusoidal waveform assumption. The main contribution of the work is that only few experimental measurements are needed in order to implement the advanced model.

“…The main contribution of the approach is that the DC bus voltage is directly regulated via the unique action on the field current. The control is scalar and consists of just two loops [21]. The armature currents are not regulated.…”

This study deals with the modelling and the control of the hybrid excitation synchronous machine connected to a diode bridge rectifier. The set operates as a DC generator that supplies an isolated grid in embedded applications such as aircraft electrical power generation. The elaborated model includes the magnetic circuit saturation effect. The aim of the control is to maintain the DC bus voltage constant when the load and/or the speed of the rotor vary. Simulation results and experiments validate the approach. The electrical parameters of the laboratory prototype machine are identified prior to the control test.
