Electromechanical optimization of high reluctance torque variable flux machines under structural mechanical constraints

Inhalt:
A design approach for high speed variable flux machines with fiber reinforced polymer filled flux barriers is presented. To ensure high speed strength, the interfacial strength between the composite and electrical sheet is investigated, as it represents a strict boundary condition in the design process. A tool chain for a combination of electromagnetic and mechanical design is presented and its target values and boundary conditions are discussed. Measurements of the interfacial shear strength between electrical sheet and the composite are carried out and the results are investigated with respect to the design process. An optimization based on the measurement data is carried out and the results of machines with and without composite reinforcement are compared.
