Finite element implementation of induction motors in healthy and faulty conditions
The following are included in this chapter: a comprehensive formulation of the Maxwell's equations; the finite element formulations; an efficient approach to the implementation of broken bar, eccentricity and short-circuit faults in an FEM package; a discussion of the adjustments in terms of selecting a proper time step and mesh size for simulations; the inclusion of a magnetic field analysis of induction motors by providing two examples, a cage and a wound rotor (the dimensions and materials are also provided so that readers might implement the same models in their own packages); and the study of the flux density variations in different faulty conditions and various motor parts including the stator yoke, the stator teeth, the air gap, the rotor teeth and the rotor back-iron.
