This paper presents the idea of manufacturing and fabricating a controller for four phase, 8/6 poles switched reluctance motor (SRM). The experimental results drawn from this controller are showing that the efficiency is a function of the applied voltage to the stator winding due to load variation, and found the best applied voltage that produced a better efficiency by this system is 85 VDC. Th...

The combination of a 16 inch Pitot tube pump with a switched reluctance motor represents a significant development in the field of high-pressure pumping. A field proven Pitot tube pump design has been mechanically integrated with a high performance switched reluctance motor. The resulting system is approximately 40 percent of the size of the standard unit it replaces. The closecoupled pump elim...

The switched reluctance motor is a simple and robust machine, which has found application over a wide power and speed ranges in different shapes and geometries. This paper introduces a new configuration for a two phase unidirectional switched reluctance motor/field assisted generator. The proposed novel motor/generator consists of two magnetically independent stator and rotor sets (layers), whe...

In this paper a fuzzy expert system for predicting the performance of a switched reluctance motor has been developed. The design vector consists of design parameters, and output performance variables are efficiency and torque ripple. An accurate analysis program based on Improved Magnetic Equivalent Circuit (IMEC) method has been used to generate the input-output data. These input-output data i...

Torque ripple minimization of switched reluctance motor drives is a major subject based on these drives’ extensive use in the industry. In this paper, by using a well-known cascaded torque control structure and taking the machine physical structure characteristics into account, the proposed energy-based (passivity-based) adaptive sliding algorithm derived from the view point of energy dissipati...

In this paper, a new magnetic structure for switched reluctance motors is presented. In this structure, both stator and rotor has a segmented topology and there is no magnetic flux path between two stator/rotor segments or any possible combination of them. The proposed segmental structure may be considered with different number of phases as well as different number of segments per phase for any...

This paper presents a flywheel energy storage system, which uses a switched reluctance motor/generator. It is shown how this device can be used either together with a DVR or alone in order to attenuate the effects of voltage sags and short interruptions. In order to improve the system efficiency, some design alternatives are presented. Finite elements analyses results, validated against laborat...

Green house effect has becomes a serious concern in many countries due to the increase consumption of the fossil fuel. There have been many studies to find an alternative power source. Wind energy found to be one of the most useful solutions to help in overcoming the air pollution and global. There is no agreed solution to conversion of wind energy to electrical energy. In this paper, the advan...

In the paper the main analytical models of the switched reluctance (SR) machine are presented, based on geometry data, magnetic equivalent circuits and finite element (FEM) analysis results. In each case a representative example is given and finally the advantages and the weak points of each type of model are evinced.

By using the energy dissipation theory and the property of the switched reluctance motor, this paper presents a nonlinear controller for the planar switched reluctance motors (PSRM). Based on the fact that the electrical time constant is much smaller than the mechanical time constant, the whole PSRM driving system is treated as a two-time-scale system and can be decomposed into two subsystems (...
