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.

This paper presents a novel lamination concept for transverse flux machines. The advantage of this concept is that the elements can be easily plugged together. The basic principle can be applied to several transverse flux machine topologies like reluctance type as well as permanent magnet ones with surface mounted and flux collecting topologies.Transverse flux machines are optimal suitable for direct drive applications because of their very high torque density. Their speed range matches the required speed range of electrical vehicles' wheels. The provided torque of the transverse flux machine enables fast acceleration. This publication deals with two concepts of transverse flux machines for application in electrical vehicles. The first concept contains a permanent magnet excited transverse flux machine, the second a transverse flux reluctance machine. The two concepts are compared considering torque density and applicability to electrical vehicles based on a finite element method simulation. Therefore the requirements to the traction drive are derived from desired characteristic values of the electrical vehicle.

This study aims to compare the soft magnetic composite (SMC) and grain-oriented (GO) steel stator axial flux permanent-magnet synchronous machine (AFPMSM) in terms of performance and iron losses. Stator cores are manufactured using both materials to perform experimental performance tests. The produced machines are designed for pump propulsion systems in left ventricular assist devices as an application area. The machines are modeled with several analytical equations, and iron losses and performance tests are carried out with AFPMSMs, finite element methods, and experimental setups. Our findings show that the torque density is higher in the GO steel stator AFPMSMs that can produce 15.07 percent more torque. GO steel material experimentally has 20.33 percent less iron loss as SMC material since the loss value per kilogram for SMC material is higher than that for GO steel. In addition, the saturation value of the SMC material is lower than that of the GO material according to the magnetic flux density value.
