A switched reluctance motor (SRM) drive generally requires a rotor position sensor for commutation and current control. However, the use of this position sensor increases both cost and size of the motor drive and causes limitations for industrial applications. In this paper, a novel indirect position sensing technique, namely, the sliding-mode observer, is proposed for SRM drives. The correspon...

Dynamic behavior analysis of electric motors is required in order to accurately evaluate the performance, energy consumption and pollution level of hybrid electric vehicles. Simulation tools for hybrid electric vehicles are divided into steady state and dynamic models. Tools with steady-state models are useful for system-level analysis whereas tools that utilize dynamic models give in-depth inf...

Herein is described an environmental and life cycle cost (LCC) analysis of one switched reluctance motor (SRM) drive and two inverter-fed induction motor (IM) drives. The two types of drives are compared based on critical reasoning, and European Commission (EC) Regulation 640/2009 is considered. Environmental impact and LCC were evaluated according the Methodology for the Ecodesign of Energy-Us...

In this paper a low-cost sensorless control strategy of SR motor is proposed. The static flux-linkage characteristics of the motor are used for estimating the position. A number of discrepancies between the static and the dynamic characteristics of the motor are explained. In this paper the issues regarding eddy effects and mutual inductances in both static and dynamic conditions, and their inf...

In this paper, a Switched Reluctance Motor (SRM) drive system is proposed to make trade-off between torque profile and vibration amplitude. the system, power factor correction fast demagnetization are achieved using single-phase Vienna rectifier as front-end converter for SRMs with nominal voltage equal half DC-link voltage. The three-level provides doubled negative in demagnetization, resultin...

This study presents a novel Switched Reluctance Motor (SRM) drive system with power factor improvement. Recently, many of the converters with variable speed drives have no input power factor correction circuits. This results in harmonic pollution of the utility supply, which should be avoided. The effect of power factor variation in terms of harmonic content is also analyzed in this study. The ...

This paper is related to comparison of two switching techniques that can be applied to asymmetric bridge converter driven switched reluctance machine.

In this study, a double-sided linear switched reluctance motor (LSRM) drive was investigated as an alternative actuator for vertical linear transportation applications such as a linear elevator door, hospital and subway doors which move linearly and where accurate position control and rapid response is requested. A prototype sliding elevator door that is focused on a home elevator with LSRMs is...

Switched reluctance motor (SRM) is an energy converter that converts an electrical energy to mechanical energy in motoring operation and vice-versa in generating operation. When the rotor is out of alignment, the inductance is very low and the current also increase rapidly. The rotor is aligned with the stator then the inductance become very large. In the simulation results, how the rotor minim...
