“…Essentially, Figure 9 can be regarded as the equivalent ECM of Figure 2, after applying reference frame transformation. Figure 9 shows the most popular ECM of the PMSM, but its mathematical equations corresponding to the circuit model contain some errors [13][14][15][16][17]. Here, the mathematical models are modified as:…”

Permanent magnet synchronous motor (PMSM) possesses the advantages of low power loss, high power density and high torque density and, hence, has achieved broad applications in both industrial drives and home appliances. With the increasing demands for high power density, the PMSM often operates at high speed and high frequency, leading to high power loss and temperature rise. Consequently, proper consideration of power loss, including the core loss, has attracted much attention for the modelling, designing, controlling and optimizing of PMSMs. However, the widely used equivalent circuit model, capable of providing good analysis results with fast calculation, often ignores the core loss, which may lead to unsatisfactory motor performance. This paper aims to investigate the development of equivalent circuit models, with predictable core loss for PMSMs, and proposes novel equivalent circuit models, which improve the core loss prediction accuracy in the load conditions. Some thoughts about the further improvement of the models are proposed and discussed.

In order to effectively extend the mileage of pure electric vehicles, the influence of the electromechanical energy conversion principle and the dynamic control of a permanent magnet synchronous motor (PMSM) on the performance of pure electric vehicles are studied with a dual-motor drive system as a carrier in this paper. A vector control strategy based on the speed-torque-current map of a motor is proposed, considering the bus voltage fluctuation influenced by battery charge and discharge. By constructing a complete vehicle model including the dynamic control model of the motor, the power distribution control strategy of a dual-motor coupling mode considering the dynamic characteristics of the motor is developed and simulated on the MATLAB platform. The results show that the dynamic model of the motor is closer to the actual running conditions. The proposed control strategy effectively reduces the demand power, decreases the energy consumption of the electric drive system, and extends the mileage of the vehicle.

“…In the EMaFM, in cases where connecting the W a 1 and W a 2 in phase series to make a Y connection as described above, the interlinkage flux of the armature winding becomes a combination of the flux of the ferrite magnets and the flux of the electromagnets. Therefore, in consideration of these characteristics, we applied the d ‐ q axis model of a typical synchronous motor to the driving.…”

In this article, the driving characteristics of an electromagnet‐assisted ferrite magnet motor (EMaFM) are investigated using a 1.5‐kW prototype machine. The EMaFM is a new type of synchronous motor, which combines a ferrite magnet motor with an electromagnet motor. Finite element analysis and experimental results show the following. (1) A wide constant power range as well as high torque at low speeds can be achieved by assisting the torque with the built‐in electromagnet motor. (2) It is possible to reduce the losses and improve the efficiency by adjusting the field current according to the operating conditions.
