This paper proposes a new consequent-pole permanent magnet vernier machine (CPMVM), which can be regarded as combination of two conventional CPMVM with opposite polarities. Based on the simplified axial magnetic circuit model, it is verified that proposed reduce unipolar leakage flux. In order to torque ripple and improve output machine, flux barrier placed rotor machine. Then, parameters are o...

This paper addresses a basic control issue in switched reluctance motor (SRM) drives—the production of a ripple-free torque. Simple and largely model-independent conventional supply waveforms are not able to satisfy this requirement. The goal of this paper is to improve SRM dynamical performance by compensating for motor nonlinearities, while maintaining the robustness of conventional methods. ...

Abstract Switched reluctance motor (SRM) is paid more attention in industrial usage because of its simple structure and low cost. But the inherent torque vibration situation noise caused by limited application electrified vehicles, which requests sooth output. To meet demand minimizing ripple, this article presents a new direct control (DTC) method with changeable reference flux steady switchin...

Torque smoothness is an essential requirement for high-performance motor drive applications. Synchronous reluctance machines (SyRM) have high torque ripple due to non-linear magnetic circuit and saturation. Typically, in Permanent magnet the active compensation achieved by injecting a compensating current q-axis. For SyRM, injection method cancellation can be used both d-axis Howe...
