Abstract

A transient eddy current package is being extended to model rotating systems. By allowing the system to rotate, induced eddy currents must be modelled. The system being developed uses the "lock-step" approach to model the rotation. As the rotation progresses the induced voltages in the coil windings change, and depending on the driving circuit configuration, the source currents will alter. Coupling to an external system model to determine the coil currents is therefore necessary. The extensions to the eddy current model are discussed, in order to compute induced voltages, and couple to an external power system model. The mechanism whereby the coupling will be achieved is also discussed.
