Abstract

In this paper, the no-load operational characteristics of radial-flux permanent magnet generators with two contra-rotating rotors are addressed. Three different radial flux machine topologies have been qualitatively studied through a sequence of stationary two dimensional finite element field solutions. It is shown that the peak value of the induced phase electromotive force during synchronous operation depend on the angular positions of the two rotors relative a fixed reference in the stator winding.
