Axial flux permanent machine design for low speed high torque application

This paper is focused on the design of Axial Flux Permanent Machine (AFPM) tailored for low-speed high-torque applications. In particular, the design procedure is developed starting from a tooth concentrated winding topology; given its high reliability, this is an optimal solution in the context of electric torsional damping applications, where high torque values and good dynamic performance are required. Based on this winding solution, a sizing flow diagram is formulated in order to define the geometric/magnetic/electric parameters of the AFPM. This design approach is validated by an accurate FEM analysis. The sizing results positively validate the proposed method by leading to a designed AFPM characterized by satisfying power densit
