Abstract :
This Paper describes an experimental process used to produce a model in Matlab and Simulink for a prototype 8/6 switched reluctance motor, and some methods used to validate the model. The inductance, flux and torque characteristics of switched reluctance motors are nonlinear, and must usually be numerically determined from real experimental data. Torque can be measured directly or calculated from measured phase current, and rotor position, and numerically determined inductance. This paper explains how two different lookup tables are used to simulate the electrical, magnetic and mechanical characteristics of the motor. Simulation results are shown to closely agree with practical current and rotor position responses under locked and free rotor conditions. It is also explained how the validated simulation models will be used in the future design of a power converter and nonlinear torque (current) and speed control loops.
