Unified Sizing Model Approach for Radial and Axial Flux Permanent Magnet Machines

Sizing equations of radial and axial electrical machines are developed. From these equations, the main geometrical parameters of the machines are obtained from the specifications and the loads. Analytical models of the open circuit and armature reaction fields are set up and associated to the sizing equations. This results in more accurate sizing equations. An axial and a radial flux motors are sized for the same loads and the same specifications to check the effectiveness of the sizing approach. Eventually Finite Element Analysis results validate the analytical models.
