Abstract :
The value of turn-off angle is an important factor in developing positive or negative, high or low electromagnetic torque in switched reluctance motor (SRM) and leads to stable or unstable operation of the drive. This paper presents the performance of a 4 kW 8/6-pole configuration SRM drive through modelling and simulation. Normally, the turn-off angle depends upon the motor speed and is changed with acceleration. However, in this paper, the study is conducted for full load starting and stable operation of the drive with fixed turn-off angle control scheme. The simulated performance of SRM drive system is presented to analyze the effect of fixed value of turn-off angle on transient and steady state performance of the drive in terms of speed, current and torque response. The merits of fixed turn-off angle control scheme are highlighted.
