Abstract

To solve the Poisson equations for the vector potential within the end region of a turboalternator, a method based on eigenfunction expansions is proposed. Use of this method allows the effects of the shaft, outer casing and rotor endbell to be approximately represented. In addition, the effects of the stator and rotor core ends can be incorporated by means of the introduction of an airgap current, in the usual way. The stator and rotor end windings are modelled in a fairly detailed manner.
