The integration of electromechanical actuators in the aircraft systems is one of the major key-point of the aerospace industry, thanks to their advantages, such us minor weight and major efficiency: this trend is called "More-Electric Aircraft".In this paper, a PM brushless motor has been designed and analyzed to integrate in an electromechanical actuator in a regional aircraft to control aileron/spoiler surface.As first step, an accurate selection of the active material has been made in order to have the best compromise between envelope and performance. Then, an optimization of the electromagnetic design has been performed in order to maximize the torque-to-current ratio at continuous operation.A surface permanent magnets machine with concentrated windings has been chosen and the proposed motor has the magnets directly glued on the surface of the steel nut. Moreover, in order to improve the power density, the high-performance CoFe electrical steel has been selected.Accurate Finite Element analysis and thermal verification have been carried out to ensure that the sized motor could cover the overall range of required performance avoiding overtemperature during the operation.

“…The modeling of this machine and its control system will be described briefly in Section 3.1.2 as the main aim of this paper is to cover in detail all issues related to the power converter and its cooling system. The electrical and thermal machine models, as well as the control algorithm, are introduced and discussed in detail in [13][14][15]. In [13], the transient analysis of the motor-drive system is introduced, including current and torque waveforms.…”

“…In fact, a number of studies [5,[10][11][12][13] prove that they can be designed, optimized and controlled to achieve high power density, low noise, low cogging torque, high efficiency and adaptability for flux-weakening regions. Considering multi-phase PM machines, they have a variety of applications in many areas such as automobiles, robotics, renewable energies, and aerospace [14,15]. A six-phase PM motor is considered in this work.…”

In this article, an advanced multiphase modular power drive prototype is developed for More Electric Aircraft (MEA). The proposed drive is designed to supply a multi-phase permanent magnet (PM) motor rating 120 kW with 24 slots and 11 pole pairs. The power converter of the drive system is based on Silicon Carbide Metal Oxide Semiconductor Field-Effect Transistor (SiC MOSFET) technology to operate at high voltage, high frequency and low reverse recovery current. Firstly, an experimental characterization test is performed for the selected SiC power module in harsh conditions to evaluate the switching energy losses. Secondly, a finite element thermal analysis based on Ansys-Icepak is accomplished to validate the selected cooling system for the power converter. Thirdly, a co-simulation model is developed using Matlab-Simulink and LTspice ® to evaluate the SiC power module impact on the performance of a multiphase drive system at different operating conditions. The results obtained show that the dynamic performance and efficiency of the power drive are significantly improved, which makes the proposed system an excellent candidate for future aircraft applications.
