Abstract: The primary objective for this paper is to create a methodology to rapidly optimize double-stators switched reluctance motor (DSSRM). An analytical model of equivalent magnetic circuits for the air gap reluctances of aligned and unaligned positions is proposed and the optimal operation point of the magneto-motive force (MMF) can be determined. Genetic algorithm (GA) integrated of the ...
The modeling and simulation of Switched Reluctance (SR) machine and drives is challenging for its dual pole salient structure and magnetic saturation. This paper presents the input data in form of experimentally obtained magnetization characteristics. This data was used for computer simulation based model of SR machine, "Selecting Best Interpolation Technique for Simulation Modeling of Switched...
In this study, radial forces that create noise, which is a fundamental problem in Switched Reluctance Motor (SRM), are investigated. Since force causes stator vibrations and noise caused by magnetic field, new switched reluctance motor model with increased rotor poles has been designed order to reduce the acting on poles. addition, structure high torque low leakage flux compared conventional wi...
The concept of this work helps to develop a switched reluctance motor (SRM) drive. Because of salient feature like four quadrant, rigid structure, high-speed capability and low cost from other types of motors, switched reluctance motor is more predictable in high speed applications. Its on-board integrated charger is formed using the embedded motor drive components. Good driving and regenerativ...
This paper presents passive boost converter fed three phase switched reluctance motor using PI Controller. The operating mode of proposed converter circuit is discussed. The proposed converter is capable of minimizing the torque ripple because of faster excitation and demagnetization and also improving the average torque compared to the conventional converter circuit. The objective of this pape...
The energy utilization ratio (ER) quantifies the of a Switched Reluctance Motor (SRM). Calculation ER an SRM can be different from other motors as it has highly non-linear operating characteristics and uses asymmetric bridge converter. In this paper, concept for SRMs been explained first then computation methodology is presented based on co-energy stored in magnetic system. are evaluated ANSYS ...
This paper presents a new design to reduce torque ripple in Switched Reluctance Motors (SRM). Although SRM possesses many advantages in terms of motor structure, it suffers from large torque ripple that causes problems such as vibration and acoustic noise. The paper describes new rotor and stator pole shapes with a non-uniform air gap profile to reduce torque ripple while retaining its average ...
A fuzzy-logic-based turn-off angle compensator for torque ripple reduction in a switched reluctance motor is proposed. The turn-off angle, as a complex function of motor speed and current, is automatically changed for a wide motor speed range to reduce torque ripple. Experimental results are presented that show ripple reduction when the turn-off angle compensator is used.
This paper uses the flux-MMF diagram to compare and contrast the torque production mechanism in seven common types of electric motor. The flux-mmf diagram is a generaked version of the flux-linkage versus current (+i) diagram €or switched-reluctance motors. It is illustrated €or switchedreluctance, synchronous-reluctance, induction, brushless ac, brushless dc, interior PM and dc commutator moto...
This paper investigates the problem of the position control in switched reluctance motor drives. Advanced proportional-integral (PI) and proportional-differential (PD) controllers for the speed and position control, respectively, are adopted. The parameters of the controllers are on-line fine tuned according to the load torque and rotor speed, for providing high dynamic performance and precise ...
