Translations are the most common motions in several industrial branches. Usually the linear motion is generated by belt or spindle drives using rotational motors. Elasticity and backlash are the problems that hinder the accuracy of such drives. These mechanical arrangements provide low speed only. Utilization of high performance linear motors can eliminate these problems because they generate l...
This paper proposed a proportional Integral Controller for Switched Reluctance Motor Drive.PI controller is one of the conventional controller .The basic sensorless operation of the Switched Reluctance Motor Drive is usually tested by this conventional controller under steady state condition. The parameter speed of the drive is controlled and analysed with the help of this controller without an...
We evaluate an external segment-type switched reluctance motor (ESSRM) generator via simulations and experiments on actual ESSRM. In the simulation, shape of ESSRM was optimized using a genetic algorithm with two sizes varied as parameters. As result calculating 480 different shapes, it is found that model by has 1.45% higher power generation efficiency 95.08% 634W generated 2,896W than single ...
This paper presents a new methodology for modeling the inductance curves of switched-reluctance machines using cubic splines based on Lagrange form polynomials. The proposed allows estimation instantaneous and derivative in each phase machine. All steps are presented discussed, detailing information necessary its use. results an experimental computational simulation, both as motor generator, es...
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...
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...
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.
