The constant progress in calculation methods, materials and production technologies offers a new opportunity for alternative machine concepts. Axial flux machines are under investigation in current research projects because they can achieve high torque densities with a short installation length. By using composite materials in the magnetic circuit and in structural components, high-performance motors can be dimensioned on the basis of this concept. The interdisciplinary research group NEMOFASER is dedicated to the design of a double-stator axial flux machine with field-wound fiber composite rotor. The aim is to create a methodology for the competitive design of such a machine. Based on current axial flux configurations, the paper presents the preferred motor concept. By using an analytical approach, a preliminary dimensioning of the magnetic circuit is carried out. Finally, a prototype is highlighted, which was realized for model validation.
