Transient analysis of a switched reluctance motor based on 3D finite element method

The paper deals with the transient performance and control analysis of a switched reluctance motor, on the basis of 3D electromagnetic field solution, by the finite element method. The 3D FEM is very efficient and contemporary approach to an accurate computation of electromagnetic field, particularly in electrical machines. The numerical nonlinear iterative calculation of three dimensional magnetic field in the switched reluctance motor is performed by the software package FEM-3D. The transient performance analysis is carried out by using the set of solutions of the voltage balance equation for different control parameters at the change of voltage supply and rotor speed of the motor. On the basis of the transient analysis, in the paper, the optimal control parameters of the switched reluctance motor variable speed drives are predicted and proposed.
