The goal of the project is to develop a simulation and optimization system for an integrated Transverse Flux Machine (TFM) based on rear earth magnets and Soft Magnetic Composites (SMC) driven by a Power electronic subsystem that will be easily optimized to specific requirements about motor control. A system that will be able to adopt broad spectrum of machines with various input parameters as efficiency, speed, power, torque and dimension is expected as a result of the project. In the development strong view to technical feasibility and orientation to system costs will be put. We expect that the system will bring us into a possibility to develop cost effective and high performance solutions that will be possible to employ in a broad range of applications. Project activities combine multidisciplinary knowledge and technologies from the research and development fields of TFM motors. This requires modelling of a 3D parametric models based n Finite Element Analysis (FEA) that allows to perform simulations and parametric optimizations during the product development, research of properties, employment and development of production processes of SMC's and selection of permanent magnet materials. Due to its specifics motor needs adequate development of mechanical and electromagnetic parts, including selection of appropriate materials, with adequate life time. Furthermore for the development of prototypes appropriate construction of tools and precise machining of prototype SMC components needs to be considered. From the motor control view of the machine in the project Power electronics subsystem will be developed and control methods, for robust and efficient motor control, operating in all four quadrants of operation will be developed. Considering validation of subsystems and system as a whole real prototype will be developed and tested, and compared to the simulation results. On the basis of comparisons we expect to come to quite precise model in three iterations of prototypes. Final result will be robust model of a TFM that will be able to estimate precise results and perform global optimizations of the system considering a set of input parameters in a short time.
Significance for science
On the basis of parametric three dimensional finite element analysis a modeling and optimization of transverse flux electric machine was performed. Simulations and prototypes of electric machines were done by employing soft magnetic composites. Considering design limitation a less sophisticated production process of such electric machine can be achieved. On the basis of electromagnetic properties of soft magnetic materials a hysteresis model of the material was developed. By employing such a model a better description magnetic behavior of the material can be reached and consequently a more precise simulation of hysteresis losses, can achieve.
Significance for the country
With the results of the project a basis for new production technologies of electric machines was given. These technologies enable more energy efficient ways for motor production with higher grades of recycling of material and with lower energy consumption. Production of motors on the basis of soft magnetic materials can lead to higher quality and competitiveness of Slovenian producers of electric machines.
