For the permanent magnet synchronous motor used in electric vehicle wheel, in order to obtain high torque at low speed, a lot of pole pairs are designed in the structure. So the electrical angle will rotate too fast, and the commutation delay will appear apparently at high speed. The commutation process of permanent magnet synchronous motor is analyzed and the timing control according to rotate speed is deduced. A motor simulation model is built to verify the control strategy. The result shows that the strategy can effectively improve high speed performance of motor.

Rotor Losses

Purpose The purpose of this paper is to present a synthesis of the analysis and modeling of the rotor losses in high speed permanent magnets motors. Design/methodology/approach Three types of losses are as a result of eddy currents in the conductive parts of the rotor. The analysis includes their characterization and the setup of a numerical model using finite element method. The adopted methodology is based on the separation of the losses which allows a better understanding of the physical phenomena. Each type of losses will be modeled and computed separately. Findings It is possible to make a precise estimate of the different losses in the rotor while keeping a relatively short computing time. Research limitations/implications The analysis is applied on a high-speed permanent magnet motor for avionic application. The model is validated with the commercial finite element model (FEM) software Flux2D. Originality/value The developed model allows an important save in terms of CPU-time compared to commercial FEM software while staying accurate. The separation of each losses and their sources is important for motor engineers and was requested for them to improve the designs more easily.
