| Abstract |
An effective switched reluctance drive simulation must be able to accommodate parameter changes to the converter as well as the motor geometry. ln the latter case a new set of magnetization curves must be generated. This paper proposes a new method capable of calculating the flux-linkage value based on user selected geometry, magnetic material and rotor angle information. Polar coordinate based none uniform finite difference node grids are assigned to the rotor and stator which are specifically suited to the switched reluctance motor geometry. The coefficient matrices for both grids are obtained using Maxwells current equation in its integral form. The node potontials for the overlapping grids are found by iteratively solving the coefficient matrix equations using a conjugate gradient method. Results obtained with the new method are compared with those found using a finite element method. |
