Abstract

This paper discusses non-conforming sliding interfaces for motion in combination with a magnetic scalar potential formulation. Lagrange multiplier are used to implement the relative motion of stator and rotor. The utilization of the specific Lagrange multiplier approach implies the application of a magnetic scalar potential formulation in 3D Finite Element (FE) modeling of electrical machines because up to the present a canonical definition of biorthogonal basis functions for the magnetic vector potential is not available.
