A switched reluctance motor (SRM) drive generally requires a rotor position sensor for commutation and current control. However, the use of this position sensor increases both cost and size of the motor drive and causes limitations for industrial applications. In this paper, a novel indirect position sensing technique, namely, the sliding-mode observer, is proposed for SRM drives. The correspon...

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...

Herein is described an environmental and life cycle cost (LCC) analysis of one switched reluctance motor (SRM) drive and two inverter-fed induction motor (IM) drives. The two types of drives are compared based on critical reasoning, and European Commission (EC) Regulation 640/2009 is considered. Environmental impact and LCC were evaluated according the Methodology for the Ecodesign of Energy-Us...

OF THESIS FPGA BASED CONTROL OF HIGH TEMPERATURE SWITCHED RELUCTANCE MOTOR FOR IMPROVING THE INPUT POWER QUALITY This thesis develops a hardware circuit implementation of a novel algorithm for reducing a SRM drive’s input current ripple or equivalently to improve the SRM drive’s input power quality. The algorithm requires the SRM’s phase current to follow a trapezoidal trajectory relative to th...

Switched reluctance motor (SRM) has many specific advantages and has being gradually used in many kinds of applications. However, because it’s inherently multivariable, strong coupling and highly nonlinear, there are lots of difficulties to build its model. In this paper, the basic operating principle of SRM are briefly introduced firstly, and then numerical and analytical modeling methods are ...

The Switched Reluctance Machine (SRM) based electrical drive systems are ideal for diverse automotive safety-critical applications where the fault tolerance is a basic requirement. The phase independence characteristics of the SRM enable it to operate under partial phase failure conditions also in its classical construction. Its reliability can be improved by applying special fault tolerant des...

An incremental motion control problem, specified by a trapezoidal speed command profile using multisegment sliding mode control (MSSMC), is proposed to control synchronous reluctance motor (SRM) servo drive. Since the control gains in the MSSMC are fixed, chattering responses occur due to large external load disturbances. Therefore, a neural network (ANN) is developed to tune the control gains ...

The purpose of this paper is to introduce a different type of converter circuit used to drive switched reluctance motors. It continues with detailed discussion on the resonant converter armed at minimizing or eliminating the transistors switching losses. Finally the drive has been tested on a disc-type reluctance motor for the perfomance and functionality.

Received Nov 1, 2014 Revised Mar 4, 2015 Accepted Apr 1, 2015 A Single Phase Switched Reluctance Motor is more popular in many industrial purposes for high speed applications because of its robust and rugged construction. For low cost and variable speed drive applications SRM are widely used.Due to doubly salient structure of motor, the torque pulsations are high when compared to other sinusoid...

The prediction of switched reluctance motor (SRM) performance requires knowledge of core losses. However, the calculation of iron losses in SRM is especially complex first because the flux waveforms are nonsinusoidal and different parts of the magnetic circuit have different waveforms and second because they are conditioned by the type of control used. This study proposes an analytical method f...
