The paper deals with the analysis of the single-phase induction motor of Problem No. 30a of the COMPUMAG TEAM Workshop. The problem has been solved by the motional two-dimensional time-harmonic Finite Element Method (FEM) using different potential formulations, the A , V - A , -potential formulation and the T , Φ - Φ -potential formulation. Here the problem is a linear eddy current field problem.
