“…These specific coefficients are calculated using theoretic expressions [15] (considering laminations of thickness 0.3 mm) corrected by measurements [8], [16], [17]. For the soft magnetic composite (SMC) machines, the coefficients (with the subscript SMC), neglecting eddy current losses, will be equal to…”

In this paper, a novel methodology is presented in order to design a permanent magnet synchronous machine associated with a gearbox for a screwdriver application. The study shows how, from specification such as maximum volume, maximum heating, torque, and speed profiles, it is possible to formulate the sizing problem. The modeling is based on a purely analytical formulation. We will show that it is possible to establish rules in order to make optimal choices of materials (magnets and stator core). The optimization of the pole pair number and the choice of the gear ratio will also be discussed. Finally, the finite element method will be used to validate the designed machine.Index Terms-Analytical models, design methodology, energy efficiency, frequency conversion, high-speed permanent magnet synchronous motor, machine tool, magnetic losses, soft magnetic materials.

“…Thus, it can be claimed that AFHESM with axial auxiliary air‐gap is more convenient to work with high MMFs. Competitive efficiency values have been reported in the literature for prototype machines at low power levels such as 86.7% at 3 kW [22] and 87% 8.9 kW [23]. Efficiency increases as the power rating goes up.…”

Hybrid excitation synchronous machines (HESMs) are permanent magnet machines which allow the control of the air-gap flux density. In this study, three new axial field HESM structures, each having two rotors and one stator, are proposed. The operation principles of these machines, considering weakening or supporting the air-gap flux density, are described. The magnetostatic and transient analyses of the proposed models have been carried out by using finite element method. To have reliable analysis results, the stator length and input and output diameters of the models have been chosen to be identical. Results are compared in terms of efficiency, power density and range of flux control between each other and another axial field HESM in the literature. In conclusion, the proposed HESM models demonstrate satisfactory performance for the generator mode and they are suitable for wind energy applications. Furthermore, because of their field weakening operation ability they can be used as motors in the vehicle industry.
