Madhu 02 04 The main purpose of studying variable drive systems with Switching Reluctance Motors SRM for torque density enhancement and efficiency improvement focuses on minimizing torque fluctuations This ripple occurs due to the change in excitation current between adjacent phases A smooth torque requires exact control of how switches turn the motor on and off Simulation of all possible angle selection consequences appears in this researchThe excitation current shape in the stator coil and its overlapping point with its adjacent coil depends on how precisely the turnon and turnoff angles are selected as illustrated by the case of extended turnon and turnoff excitation timing Correct selection of turnon and turnoff angles enables the implementation of transition phase smoothness Researchers have performed a comprehensive analysis to determine how the modified excitation current interacts with torque ripple based on different dwell angle conditions Proper selection of these parameters leads to the generation of sinusoidal current forms Copyright (c) Journal of Science Engineering Technology and Management Science.
