Propose Two Methods To Find Values of The Aligned And Unaligned Inductance of The Switched Reluctance Motor

Abstract

Aligned and unaligned inductances of SRM are needed for modeling and simulation program. Two simple methods have been suggested in this research to measure value of these inductances. It has been compared between two method depending on the shape of the motor current taken practically with the simulation current after compensating the value of the inductance in the simulation model and chose the most accurate method to measure the inductance. The values of the aligned and unaligned inductance in both methods in sequence are (101, 70, 74.5, 59.5). Through compensation the inductance values in the simulation model and compare the performance of this model with the practical performance, it was reached that the first test the nearest 93% of the practical value compared with the second test, which reaches matching ratio to 79%.The specification motor used was: type motor-SRM80L, Power rated=550watt, Number of phases=4, Number of poles 8 in stator and 4 in rotor, rated speed=1000rpm, rated torque=5N.m, rated current=4.5A, Driver AC=230v, Motor DC=285v.
