Abstrakt
In this paper, an analysis of the properties of a switched reluctance motor (SRM) 8/6 in an extended constant power range is presented. The typical constant power range to constant torque range ratio is between 2 and 3. In the case of machines designed as an electric vehicle drive, it is important to maximize this ratio. In the case of an SRM, it is possible to achieve this by applying an appropriate control strategy. An analysis of the SRM operation utilizing a modified control algorithm allows control of the maximum value of the motor phase current. As a consequence, using the so-called nonzero initial conditions for the current and flux allows the output power to be maintained in a wide speed range. For the improvement of drive system efficiency, the work of the phase current regulator should be limited to a minimum. The most advantageous work conditions we obtain with single-time current regulator work. Laboratory verification has been performed for selected states of motor work.
