Abstract

The paper describes the design of a microalternator in which negative-resistance devices are employed to obtain representative constants of the model´s rotor circuits. Dimensional scaling in assessing the parameters of model alternators is reviewed. Methods of calculating the model´s principal constants from design data are outlined for a machine of salient-pole-rotor construction. Core and short-circuit losses are examined, and the choice of design criteria is discussed. Test results for a machine of salient-pole construction are given which compare very favourably with the constants derived from design considerations. Attention is also given to the special facilities which are provided by the time-constant regulator and other associated auxiliary equipment.
