SWITCHED RELUCTANCE MOTOR-DRIVES - RECENT ADVANCES

The objective of this paper is to review the state-of-the-art and rece nt developments in Switched Reluctance Motor (SRM) drives. The interes t for improved performance and reliability has motivated many SRM adva nces in the recent years. Even after almost 30 years of research in SR M, which might appear to be the simplest of all machines, there remain critical issues to be explored to gain deeper insight into the SRM te chnology. The paper briefly discusses the historical background and th e basic operating principles of the motor. The topics discussed includ e the current state of research in converter topologies, control algor ithms, torque ripple, noise, and sensorless operation. Recent advances in the field of SRMs indicates that they will have an increasing infl uence in the area of variable speed drives in the coming decades.
