The purpose of this paper is to propose an interesting combination of two different types of switched reluctance generators (SRG) as a suitable prototype to produce electrical energy using variable speed energy resources such as wind turbines. The paper focuses on the amount of electric efficiencies of these two generators when they are utilized as the suitable candidates to produce electric power...
In this paper a novel view of airgap magnetic field analysis of Switched Reluctance Motor under static eccentricity to provide the precise fault diagnosis based on three-dimensional finite element method is presented. Analytical nature of this method makes it possible to simulate reliable and precise model by considering the end effects and axial fringing effects. The results of the three-dimensional...
This paper presents a novel method to indirectly detect the rotor position at standstill and also at low speeds in a field assisted switched reluctance motor. In this method, a high frequency sine wave signal is applied to the field assisted winding on the stator and then the phase of induced signals on each phase winding is monitored to detect the rotor position at standstill. The method utilizes...
This paper presents a new configuration for switched reluctance motor, which has no direct windings on the stator poles. The motor has three different layers and each layer has only one concentric winding. The magnetic field passes through a guide to the rotor then the stator and finally completes its path via the motor housing. To evaluate the motor performance, two types of analysis, namely the...
This paper presents the comparison results between two new motor/generator configurations. These motor/generator units are a field assisted switched reluctance motor (SRM) and a brushless dc (BLDC) motor without permanent magnet. The proposed SRM and BLDC consist of two stator and rotor sets (layers). To evaluate the motors performance, two types of analysis, namely, the numerical technique and the...

The switched reluctance machine is a simple and robust machine, which has found application over a wide power and speed ranges in different shapes and geometries. One of the most important characteristics of switched reluctance machine is the ability of this machine to be used in generating mode which is known as switched reluctance generator (SRG). In this study, a novel switched reluctance generator...

This paper presents a novel method to estimate the rotor position of a new field assisted switched reluctance motor at standstill and also low speeds. In this method, a high frequency sine wave signal is applied to the field assisted winding on the stator and then the phase of induced signals on each phase winding is monitored to detect the rotor position at standstill. It then continues to sense...
