Switched reluctance motor drives — recent advances

Digital Control of Switched Reluctance Motor Drives

drives are designed to increase product performance and system efficiency. One such motor type which can benefit from digital control is the switched reluctance (SR) motor. The SR motor brings advantages in both cost and reliability over other types of adjustable speed drives. These include its simple mechanical construction, high efficiency and high power density. On the other hand, large torq...

Conventional Controller Design for Switched Reluctance Motor Drives

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...

A New Sensorless Method for Switched Reluctance Motor Drives

This paper describes a new method for indirect sensing of the rotor position in switched reluctance motors (SRM’s) using pulsewidth modulation voltage control. The detection method uses the change of the derivative of the phase current to detect the position where a rotor pole and stator pole start to overlap, giving one position update per energy conversion. As no a priori knowledge of motor p...

Acoustic Noise Reduction of Switched Reluctance Motor Drives

This paper presents a simple and novel procedure for acoustic noise reduction in Switched Reluctance Motors (SRMs) drive. The main sources of acoustic noise in a SRM are the radial magnetic force and torque ripple. To investigate the radial force, an analytical relationship between motor designs and drive parameters is required. Thus, in this method two mathematical methods for calculation of r...
