Fluid mapper에 의한 철극형 전기기기의 자극 주변에서의 자속분포의 결정

Determination of Magnetic Flux Distribution around the Salent Pole by means of the Fluid Mapper

Field problems are solved by a variety of methods. In the relatively small number of cases that are simiple enough, the mathematical attack may be the method of choice. But many field problems with irregular boundary condition must be handled by the use of the electrolitic tank analog, conducting paper or the fluid mapper analog for the purpose of effectiveness and convenience. The method of choice depends on the actual of the problems. There is no one best way to solve all problems. The following points have been described in this apepr, 1. Theoretical studies are made of the vector which is produced by leading the fluid flow vector by a right angle. 2. Curvilinear square method is described., 3. Determination on magnetic flux distribution and variation according to the magnitude of exciting currents.
