Switched reluctance drives: new aspects

A 1 kW switched reluctance motor drive and an efficient power converter requiring only a low number of switches are introduced. An analytical model of the interactive behavior of the motor and the power converter is developed. The drive is to be essentially torque controlled. The goodness factor of the motor (which expresses how effectively the voltamperes available from the power converter are used for active power conversion) is introduced. In order to increase the goodness factor, premagnetization is applied. The controllability of torque and the premagnetization principle is evaluated by experiments and are found to agree with the theoretical model.<
