This paper shows how a time-dependent and non-linear simulation of the dynamic operation behavior of an induction machine is executed by means of the "Rotating Machinery" interface from COMSOL Multiphysics 4.2a. The two-dimensional FEM model is connected to electrical circuits by coupling the physics "Rotating Machinery" and "Electrical Circuit" interfaces. These circuits include the lumped electrical components to simulate the electrical effects in the end area as well as the three-phase-voltage system to supply the stator. Simulations are made for constant slip values as well as dynamical start-up with an additionally defined equation of motion as an ordinary differential equation by means of the "Global ODEs and DAEs" interface.
