INFLUENCE OF SIZE AIR GAP A THREE-PHASE
SYNCHRONOUS GENERATOR THE TOTAL COST OF ITS
The total cost of a three-phase synchronous generator, containing the
cost of manufacturing and operating costs throughout its life, depends on the
size of the generator and its air gap. The air gap is size with a small value
compared with dimensions of synchronous generator, but is strongly influenced
by electromagnetic requests. In this paper we aimed to analyze the influence of
air gap variation on overall dimensions, mass of active materials, loss of these
and implicitly on the total cost. This analysis was possible after writing a
program for optimal design of synchronous generator using MathCAD software.
