A Quasi-3-D Finite Element Modeling of An Axial Flux Magnetic Resonant Motor

Due to inherent the 3-D magnetic structure of axial flux machines (AFM), 3-D finite element analysis (FEA) is the most commonly utilized approach for simulation in the design and analysis. However, these simulations are exceedingly time-demanding, particularly during the early phases of the design. This challenge has not been properly addressed in the design of an axial flux magnetic resonant motor (AFMRM). This in turn has limited the level of optimization that has been achieved in the design of AFMRM motor. In this paper, we present a method to quasi-3-D conduct FEA modeling analysis of an AFMRM motor. It is achieved by slicing the 3-D geometries of the AFMRM machine with cylindrical planes of different radii to form equivalent 2-D linear machine (2DLM) models. The magnetic problem is then solved in each slice with a 2-D finite element method (FEM). As a result, the generated mesh required for computation is faster and many designs analysis can therefore be implemented for optimization.
