Technology, Research and Applications of Switched Reluctance Drives

Abstract

Abstract-Electrical drives are one of the major consumers of electrical energy and their penetration in the market is still growing. Hence, for many drive applications efficient, reliable and cost effective solutions have to be found. Switched reluctance drives (SRD) offer a potential solution when focus is mainly on cost and robustness. However, to benefit from the unique advantages of this machine type a deep understanding of its strongly non-linear behavior is required. After discussing some major differences to classic rotating field machines, this paper presents a broad overview of the state of the art of SRD taking into consideration all aspects relevant to machine modeling, design and control development process. Finally, applications on the market utilizing SRDs and the focus of current research is presented. After reading this paper the reader will be able to assess if this modern drive technology could be advantagous in a given application.

Design of a high speed 18/12 switched reluctance motor drive with an asymmetrical bridge converter for electric vehicles

“…In the machine design the main challenge and limiting factor is thermal constrain due to winding on stator and rotor [13]. There is a great interest in machines with reduce mass of magnet or having no magnet, in general for current technologies the switched reluctance machines have pushed the boundaries for traction motor drives applications due to simple and robust construction, absence of demagnetization, no copper winding on the rotor with the main focus on cost, robustness and high temperature environment applications [14]. The main advantage of SRM is a very extensive field weakening area, up to 10 time has been appealed.…”

“…In order to meet the demand, now a days there is more attention in the low cost switched reluctance motor drive system because of several advantage such as robust construction, normally cheap, design simplicity, no winding on rotor and absence of demagnetization which is the most suitable for electric and hybrid electric vehicle [14,22,[26][27][28][29][30].…”

Switched Reluctance Motor Modeling and Loss Estimation Review

“…Analytical models and lookup tables are much faster but have reduced accuracy. Therefore, SRM modeling must be addressed as a trade-off between simulation accuracy and computational speed [6].…”

Analysis and Design of a Speed Controller for Switched Reluctance Motor Drive

“…It is concluded that improving the SRM control strategy is a more cost-effective way to deal with the SRM noise and torque ripple. The main aspects of machine modeling, design and control are very well presented in Burkhart et al (2017). The most appreciated advantage of this motor is the non-use of neither rare elements nor windings on the rotor.…”
