The design procedure of two different double-stage Magnetic Gear Transmission systems (MaGTs) is presented in this paper. The MaGTs are characterized by the same maximum input torque and speed, but by different Permanent Magnet (PM) materials, namely NdFeB and Ferrite. The design procedure consists of optimizing the MaGT inner and outer stages sequentially, by selecting the cheapest configurations among all those that comply with both mechanical and magnetic constraints. The performances of the designed MaGTs are determined and compared to each other by both an analytical approach and Finite Element Analyses (FEAs), which are carried out by means of FEMM and SolidWorks software. The comparison reveals the most important advantages and drawbacks of each configuration, together with their possible future developments.

To minimize eddy current losses, stators and rotors are traditionally designed laminated. For this purpose, the single sheets are electrically separated from each other by an insulation layer. The production of electrical steel laminations for rotor and stator stacks is divided into the steps of cutting, stacking and joining. Currently, there are several possibilities for each process step. The selection of the suitable process depends on the application, quantity and size of the electrical steel laminations. In mass production, the electrical steel strip is separated mainly by stamping. In prototype manufacturing and for small series, the lamination is cut out by laser. In addition, wire EDM and water-jet cutting are applied in specific applications. Rotary cutting of electrical steel strip is a process that is not yet used in industry. However, the novel approach has a great potential, since investment and tooling costs are relatively low. Furthermore, the process is suitable for the production of thin laminations (smaller than 0.3 mm) which are used in traction motors for electric vehicles.
