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...

Abstract Aiming at the problem of jitter in speed when load changes abruptly during operation a synchronous reluctance motor and poor resistance to disturbance, an integral type sliding film variable structure control algorithm is proposed. The regulation controlled by mode, PI controls current regulation, Simulink simulation model system built, experiments are conducted. results show that, com...

This document deals with solutions to control a switched reluctance motor using the TMS320C24x. This new DSP family enables cost-effective design of intelligent controllers for switched reluctance motors. Two speed control algorithms are presented, they allow the Switched Reluctance motor drive to reach high efficiency, smooth operation, very good dynamic behavior, very high speed and low acous...

Switched Reluctance (SR) Motor Drive is of great topical interest. It has the potential lo emerge as a viable option for variable speed applications. Though simple in construction, the motor is quite rugged, and has many attractive /eatures like high torque-to-inertia ratio, fault tolerance, and high eficiency. A number of converter topologies are prescribed for driving the motor. However, its ...

November 2003 The L297 Stepper Motor Controller is primarily intended for use with an L298N or L293E bridge driver in stepper motor driving applications. It receives control signals from the system’s controller, usually a microcomputer chip, and provides all the necessary drive signals for the power stage. Additionally, it includes two PWM chopper circuits to regulate the current in the motor w...

This paper deals with the analytical computation of the magnetic field distribution in a wholly superconducting reluctance motor. The rotor is made with high temperature superconductor bulks which nearly present a diamagnetic behavior under zero-field cooling. The stator consists of superconducting armature windings fed by AC currents of high amplitude. The superconducting stator winding can ge...

Switched reluctance motor (SRM) drive has remarkable characteristics that make it attractive for high-speed applications. As the motor's speed increases the shape of the current waveform changes in such way that limits the production of motoring torque. At high speeds, it is possible for the phase current never reaches the desired value due to the self e.m.f. of the motor, therefore, the torque...

This paper demonstrates the implementation of low cost switched reluctance motor (SRM) drive and application of RT lab as real time hardware-in-loop (HIL) controller. Split DC converter and positioning sensing arrangement is developed for 500W 8/6 pole SRM. Control part is implemented using Opal RT Lab technology. Application and optimistic characteristics of proposed low cost drive are describ...
