Study and performances analysis of magnet design on rotor surface of permanent magnet synchronous machine (PMSM) based on finite element method (FEM) is presented. Three-phase PMSM has been investigated and numerical simulation performed using FEM with the aid of ANSYS Maxwell 2018.1 software. This research presents the positional variation of permanent magnets and their effects on the performance of the three-phase PMSM. The FEM is used as a technique for simulation besides the possibility of dealing with nonlinear equations. The PMSM involves a complex electromagnetic reaction, the authors used the ANSYS program to analyze and represent the performance of the motor under variable conditions. The case studied in this proposal is for three phases 220V, 50Hz, 0.55kW PMSM. Five rotor topologies namely, (i) spoke/tangential, (ii) saturable bridge/ U-shape (iii) V-shape (iv) radial, and (v) segmented bridge permanent magnet (PM) rotor is considered in the study. The aim of this research is to investigate the effect of a variety of rotor designs with different positions of magnets on efficiency, phase current, air gap magnetic flux density, and torque of PMSM. The ANSYS software has been used to model and simulate all topologies considered. In addition to the overall efficiency at steady state, electromagnetic and mechanical parameters are evaluated for each topology and comparative results are reported. The developed 2-D model shows the magnetic field distribution and performance of operational parameters under transient and steady-state conditions. The rotor shape with the smallest magnet volume is highly affecting the torque, magnetic flux, efficiency, and torque ripple. Radial force distribution with demagnetization of PM is also studied and results are reported. The obtained results show that significant changes in motor performance because of variation of PM design.

“…However, this method has some limitations due to the nonlinear effects of the drive circuit. The limitations of voltage boosting are mainly caused by SoC and the thermal structure of a battery pack, winding resistance, non-ideal effects, and voltage drops of semiconductors [25]. Battery heating is dependent on ambient and operation conditions [26].…”

The brushless direct current (BLDC) machines which are preferred in light electric vehicles (LEVs) come forward as high regenerative braking capability machines due to their permanent magnet excitation and relatively simple operation. In this paper, the regenerative braking capability limits of BLDC machines and their drive circuits are examined by taking into account nonlinear circuit parameters and battery internal resistance variation. During energy recovery from mechanical port to electrical port, the inverter of BLDC machine is operated as a boost converter which enables power flow to a battery. However, the regeneration performance is also heavily dependant on the battery condition, particularly the temperature. By means of the developed detailed circuit model including the non-ideal effects of the boosting converter and the increase of the internal resistance variation which is caused by the temperature variation of the battery and ambient temperature, the specific duty cycle can be determined. The specific duty ratio is then applied in a proposed approach for various operation scenarios. The experimental tests are implemented by a 400 W BLDC machine drive system controlled via a TMS320F28335 digital signal processor. The experimental results show that the proposed comprehensive model presents a proper performance estimation of regenerative braking system under varying battery temperature.
