Abstract

This paper presents the influence of 6/4 and 12/8 switched reluctance motor (SRM) topologies on the motor torque ripples of electromechanical brake system. The SRM drive was developed on MATLAB/SIMULINK platform. The SRM models were parameterized with FEM data of the motor magnetic flux as a function of current and rotor angle. These data were computed by 2D electromagnetic field finite element tool, MotorSolve. The unaligned inductances of 6/4 SRM and 12/8 SRM at 200 A were 1.31 mH and 2 mH, respectively, while their aligned inductances were 2. 5mH and 3. 82mH, respectively. The obtained simulation results showed that 12/8 SRM has better response in terms of torque ripple reduction over wide speed range. Furthermore, the influence of the stator pole embrace on torque ripples was studied. Simulation results depicted that the torque ripples of both topologies can be reduced by changing their stator pole embrace from 0.45 to 0.50. There were 44.5 % and 46.3 % reductions in torque ripples of 6/4 and 12/8 SRM respectively, considering the two stator pole embraces at speed of1500 rpm and load torque of15 Nm. These findings indicate that the 12/8 SRM design is optimal in electromechanical brake system in terms of torque ripples minimization.
