“…Note that the scientific debate on optimal machine topology remains open. This is because of the well-known demagnetization problem of permanent magnets at higher temperatures, rendering other types of machines, such as switched reluctance machines and extremely attractive [13], [14]. In any case, the use of a synchronous machine to supply three-phase electric grids may decline.…”

“…An electric machine, usually a synchronous generator [44]- [46], is coupled to the main engine to accelerate the rotor from a standstill until the start velocity (ωstart in Fig. 13) is attained (other machines, such as induction [47], [48] and switched reluctance machines [13], [49] with bidirectional power electronics, are also linked). Once the engine reaches the appropriate velocity, self-sustaining combustion can occur.…”

Aviation is a significant contributor to greenhouse gas (GHG) emissions in the transportation sector. As the adoption of electric cars increases and GHG emissions due to other modes of transport decrease, the impact of air travel on environmental pollution has become even more significant. To reduce pollution and maintenance, and ensure cheaper and more convenient flights, industry and academia have directed their efforts toward aircraft electrification. Considering various types of aircraft, several frameworks have been proposed: more-electric aircraft (MEA), hybrid electric aircraft (HEA), and all-electric aircraft (AEA). In the MEA framework, propulsion is generated by a conventional jet engine; however, all secondary systems (hydraulic, pneumatic, and actuation) are electrified. By further increasing electrification, electric motors can provide propulsion with the electric power supplied by the conventional engine (i.e., HEA) or from electrical energy storage (i.e., AEA). Power electronics and electrical machines play a key role in this scenario in which electric power must be efficiently generated, distributed, and consumed to satisfy extremely high requirements of aviation safety. This article provides an overview of recent advancements in aircraft electrification, and trends and future developments referenced to the global aviation roadmap.

Owing to the robust structure of switched reluctance machines, high-speed operations are preferred to achieve higher power densities. Generally, at high speeds, single pulse control is applied. However, its control parameter set is not unique. This paper proposes an algorithm based on design of experiments that simultaneously allows the calculation of optimal control parameters for an operating area and the minimization of the total machine losses. The designed experiments are finite-element analyses (FEAs) considering both iron and copper losses. A Pareto search algorithm solves the proposed multi-objective optimization problem. The results for different response surfaces are compared considering the errors in torque production and machine loss prediction. A reduced response surface based on 15 FE-runs shows a mean error of 1.9%, whereas the maximum error is 6.3% for machine losses within the validation operating area.
