� 2016 IEEE. How to impose gauge condition properly to ensure the uniqueness of the magnetic vector potential (MVP) formulation is a key problem to investigate. Traditional Coulomb gauged formulation using penalty technique is not valid for edge elements since the divergence of the edge element basis is zero within each element. In this paper, a novel gauged formulation for motional eddy-current problems using edge element is proposed. For the proposed method, the resultant linear system is uniquely solvable by direct solvers robustly. A numerical example is presented to showcase the accuracy and usefulness of the proposed method for practical engineering computation.
