Abstract

An apparatus for changing the operating modes of a switched reluctance motor is disclosed. The motor can be operated in either a multi-phase mode or a single-phase mode. When the motor is operated in a multi-phase mode, all stator windings are energized, however, when the motor is operated in a single-phase mode, only the windings corresponding to a single phase are energized. The apparatus includes a logic circuit (146) for sensing the motor speed, and a comparator circuit (172) for changing the motor operating modes. The mode change is based on the speed levels of the motor. Between the speed levels, there is a hysteresis operating band to prevent undesirable hunting between the single-phase mode and the multi-phase mode.
