In this paper, a claw pole permanent magnet machine is studied using a 3D scalar potential formulation. First, the discretisation of Maxwell's equations using Whitney's elements is presented. Especially, the method to take the winding current distribution into account by means of source fields is detailed. Then, a numerical model of the studied machine is presented. Simulation results (inductance, EMF, torque) are discussed by comparison with experimental ones.
