Wide-bandwidth measurements are necessary when testing electronically switched drfves. 7 b o dfficult pmblems are addressed the measurement of motor phase input power at low speed. with a high PWM modulation frequency and the measurement of small torque ripple (superlmposed on a large mean toque). In an electrlcdlY noisy envlronment. Extensive use Is made of dlgilal signal processing techniques...

Due to their advantages, switched reluctance motors (SRMs) are interesting solutions for electric vehicle (EV) propulsion. However, they have the main drawback of high torque ripple. This paper develops a universal control (UTC) technique SRM that can fulfill all requirements under wide range speeds. The developed UTC involves two different techniques. It utilizes direct instantaneous (DITC) st...

Switched Reluctance Motors (SRM) have inherent advantages such as simple structure with non winding construction in rotor side, fail safe because of its characteristic which has a high tolerances, robustness, low cost with no permanent magnet in the structure, and possible operation in high temperatures or in intense temperature variations. The torque production in switched reluctance motor com...

In this study, radial forces that create noise, which is a fundamental problem in Switched Reluctance Motor (SRM), are investigated. Since force causes stator vibrations and noise caused by magnetic field, new switched reluctance motor model with increased rotor poles has been designed order to reduce the acting on poles. addition, structure high torque low leakage flux compared conventional wi...

Abstract: This paper presents a characteristics analysis and performance comparison of high-speed two-phase 4/2 and hybrid single-phase 4/4 switched reluctance motors (SRMs). Although the motors are advantageous as high-speed drives, both conventional structures have high torque ripple as a result of the presence of the torque dead zone. In this paper, solutions to the torque dead zone problem ...
