“…The asymmetric half bridge converters require a higher number of current sensors and connection leads than the conventional voltage source inverter for the same phase number [24], leading to increased mass and volume. However, recent research has focussed on utilizing conventional VSI technology with higher phase number switched reluctance motors to reduce the number of connections and current sensors [25,26]. The converter VA requirement of a VSI for synchronous reluctance machines is obviously greater than that for an equivalent size induction machine, due to their lower power factor.…”

Despite the many benefits, high torque ripple and low power factor reduce the topologies desirability and are identified as an area of further research.

“…The switched reluctance machine has the benefit of single tooth coils with short end windings but requires a non-standard converter, the Asymmetric HalfBridge (AHB) -this converter cannot be purchased off the shelf and is one of the reasons the SRM cannot claim mainstream acceptance and is mainly utilized in special applications. Other issues include the number of current carrying connectors required; the SRM requires two leads per phase [20], where as a conventional AC machine requires only one per phase. The SRM typically requires a separate current sensor per phase and the conventional AC machine does not.…”

Abstract: In recent years, the desire for high efficiency and high torque density electric motors without permanent magnet materials for the industrial, as well as the specialist product sectors, has increased significantly and has developed into hot research topic. This paper discusses a reemergent type of AC electrical machine, the Synchronous Reluctance Machine. Current EU legislation aims to tackle global energy usage and reduce greenhouse gas emissions, the Synchronous Reluctance motor is discussed in this context -Its potential to become the future industry standard for high efficiency, low cost, high output industrial drives for fan, pump and mill type industrial applications is explored. The reader will be brought up to speed with Synchronous Reluctance technology, presented with both its advantages and disadvantages with the suitability of the technology for industry application being discussed and a comparison made with respect to competing technologies -the traditional induction machine and the modern permanent magnet machine. Current and future research trends are outlined and a simple engineering case study is also presented as an indication of the energy saving potential of this type of machine. This paper aims to inform students, engineers and key-decision makers in industry about this exciting technology.

“…More recently, a configuration has been proposed which enables a six-phase SRM to be driven with a three-phase full bridge inverter, thus reducing torque ripple without recourse to a non-standard converter [26]. Alternative winding connection types were investigated for this drive and a symmetric winding pattern was proposed whereby phase windings are unconventionally connected with opposing polarities, giving rise to significant phase interaction [27].…”
