There are many methods in literature for canalizing of circulating useful flux from stator core to rotor core without radial movements in induction machines. It is obvious to healing of useful flux with decreasing radial moved zig-zag flux and it increases the motor performance. Magnetic barrier, cutout and using of slits are the most used methods for improve the circulating useful flux in the ...

Abstract eVTOLs are receiving a lot of attention as potential solution to urban air mobility challenges. Many configurations multirotors, which open loop unstable, therefore very susceptible actuator failures. Due their usually short mission duration (20-30 min), fault-tolerance the propulsion system is greater importance then reliability. Thus, novel approaches enhance this capability required...

Switched reluctance motor drive system has greatly practical value in electric vehicle applications. For the characteristics of switched reluctance motor and electric vehicle application requirements, how to reduce the torque ripple effectively and ensure its average output torque, all these become a hot spot of research. Based on this, first of all, the nonlinear model of switched reluctance m...

This paper is related to comparison of two switching techniques that can be applied to asymmetric bridge converter driven switched reluctance machine. Switched reluctance motor operation principles are discussed. Theoretical circuit operation description and Matlab simulation software are used for switching technique comparison. After analysis shows that modification of switching technique have...

This article introduces a new technique for reducing the time of calculating radial and tangential force density waves switched reluctance machines (SRMs). The method is based on finite element (FE) simulation fraction an electrical cycle. approach shows that significant reduction achieved as compared to required stator rotor calculation one mechanical cycle method. As motors introduce challeng...

Double-stator switched reluctance machines have higher torque density and lower vibration and acoustic noise level in comparison with conventional switched reluctance machines. Static characteristics of a 8/6 Double-stator switched reluctance machine have already calculated using finite element method. However, no measurement has been presented for the static torque of the machine. This paper p...

Purpose – The purpose of this work is to applicate a sliding mode observer for sensorless control of switched reluctance motor (SRM) drive Design/methodology/approach – This paper presents an evaluation of the sliding-mode observer to estimate the SRM speed and rotor position. Non-linear model of a SRM is used and a computer simulation is developed based on data from an experimental motor syste...

Experimental determination of magnetization characteristics of switched reluctance motors (SRM's) is quite important in their accurate performance prediction. Over the last decade, various experimental procedures have been used to obtain these characteristics. Every evolved new method has its own limitations and constraints. This paper describes an improved, simple and cost effective experiment...
