Abstract

This paper presents important concepts that are to be considered in designing an AC exciter of a brushless exciter. These concepts are important because, based on these concepts, such as physical proportions, magnetic flux densities, current densities and existing design performance, a method for synthesizing a group of designs can be produced for an optimal solution of brushless exciter design. Brushless exciters are multi-pole, high frequency machines with a rotating armature and a stationary field windings. Selection of exciter rating, rotor length and diameter, armature core and winding, flux level, armature slots, air gap size, armature winding connection, and winding pitch are discussed. Also, a summary table of a case study, which was done utilizing the concepts in this paper, is presented
