Simulation of a Variable Reluctance Steping Motor for Sinusoidal and Step Exitations %K Variable Reluctance Motor %K Simulation %K Excitation Voltage Dynamic Performance %R %X Steady-state dynamic simulation of a variable reluctance stepping motor is carried out by applying two different excitation voltages. First a single-step voltage is applied to the motor, and a sinusoidal voltage, as the first term of Fourier series of the single-step voltage, is then used as the input voltage of the motor. In both cases plots of machine torque, current and speed are presented. A comparison between the results of the two cases shows that a sinusoidal input voltage cannot predict the real performance of the motor, and in critical dynamic conditions, a single-step response is far from the reality. Reasons for these discrepancies arising from the various factors are discussed in the paper. %U https://www.ije.ir/article_71147_6dccf18a23e9807daee5a16e6ae33b5d.pdf
