Abstract

Permanent magnet (PM) less electrical machines are required in electric assisted turbochargers (EATs). Synchronous reluctance (SynRel) machine is a good candidate considering it is rugged and magnet less rotor structure. Saliency of a high-speed SynRel machine is impacted more by q-axis inductance (L {q}) in comparison to d-axis inductance (L {d}). Lq depends on the saturation flux density in addition to other geometrical parameters of the ribs. The impact of saturation flux density on the electromagnetic performance of a 1 kW, 60 krpm high-speed SynRel machine is analysed in this paper by considering 6 different materials. The average torque is found to increase with a reduction in saturation flux density till the decrease in Lq dominates the decrease in Ld. Further, ribs operate at higher values of saturation flux density. Therefore, the average torque is determined by the saturated BH curve of the material in addition to the knee point.
