The study presents the development and implementation of a new sensorless algorithm for estimating the rotor position at a wide range of operating conditions. The algorithm is designed to overcome difficulties in estimating the rotor position at starting as well as at the normal operation region. The algorithm is successfully implemented experimentally using SRM fed from a photovoltaic source w...

A category of permanent-magnet-shield (PM-shield) axial-field dual-rotor segmented switched reluctance machines (ADS-SRMs) are presented in this paper. These topologies featured by using the magnetic material to shield flux leakage stator and rotor parts. Besides, deployed magnets weaken saturation iron core, thus increasing main flux. Hence, torque-production capability can be increased effect...

This paper proposes an effective method of energy regeneration during braking for a dc motor or internal combustion(IC) engine. During the braking period, instead of dissipating the kinetic energy in the brake shoes and poles in the form of heat, this energy is recovered using a switched reluctance generator that is mechanically coupled to the shaft of prime mover. Here the DC motor or the IC e...

This paper investigates the accuracy of rotor-locked transient-response (RLTR)-based vibration model for switched reluctance machines (SRM). RLTR is stator stimulated by abrupt change radial force when turning off one phase SRM with rotor being locked, total can be modelled as linear superposition series. An electromechanical built to clarify generation vibration, it revealed that some velocity...

The generated torque ripple in switched reluctance motors (SRM) can be considered as one of the major disadvantages of the motor. It is mainly due to frequent switching of phases for rotation of the motor and changes of the air gap length between the rotor and stator teeth. It decreases the average developed torque, diminish the efficiency, causes noise and vibration in the motor. So, in order ...

This paper presents swarm intelligence based Adaptive Particle Swarm Optimization (APSO) technique to determine optimum design of Switched Reluctance Machine (SRM). In APSO technique, the inertia weight factor is made adaptive on the basis of objective functions of the current and best solutions to avoid premature convergence. The SRM design is treated as nonlinear multivariable constrained opt...

A multilevel modeling approach was developed for effective prediction for performance parameters of Switched Reluctance Machine. In this approach each system is described by its most efficient model.
