This paper presents a hybrid method for the calculation of eddy current losses in axial flux permanent magnet (AFPM) machines with an ironless stator. The method combines two-dimensional (2-D) finite element (FE) field solutions with the closed-form formula for eddy current loss calculation. The computational limitations of using 2-D FE modeling are discussed and a multi-slice and multi-layer FE model is developed to account for three-dimensional (3-D) effects. Relevant tests at high frequencies are carried out to validate the method. It is shown that the proposed method can predict the eddy current losses of ironless stator AFPM machines with reasonable accuracy.
