Abstract

Reactance calculation based on FEM from changing frequency point of view described here is effective on considering various kinds of transient phenomena. Moreover, electromagnetic force on the end-winding is described here to evaluate its support system, especially for large capacity cylindrical synchronous machines, where end-winding portion is the longest and electro-magnetic forces on it is the greatest of all rotating machinery.
