Design of electrical machines by using conformal mapping

Jan Šlamberger (Author), Peter Virtič (Author)

Abstract

The design of electrical machines requires good working knowledge of magnetic fields in air gaps, which is very difficult or analytically unsolvable in most cases. With the development of computers, numerical methods came to the fore, enabling very good approximations of real values to be calculated. One of the major disadvantages of numerical methods is the duration of the calculations, particularly with the construction of prototypes, in which the structure changes, thus requiring more calculations. With the goal of bringing about quicker calculations, analytical methods were used, and combinations of analytical methods with numerical methods were re-started. This article will present an analytical calculation of magnetic fields using conformal mappings.

Secondary title:	Konstruiranje električnih strojev z uporabo konformnih preslikav
Secondary abstract:	Načrtovanje električnih strojev med drugim zahteva dobro poznavanje magnetnega polja v zračni reži, kar pa je v večini primerov zelo zahtevno oziroma analitično nerešiljivo. Z razvojem računalnikov so prišle v ospredje numerične metode, s katerimi lahko izračunamo zelo dobre približke realnim vrednostim. Ena večjih slabosti numeričnih metod so dolgotrajni izračuni, še posebej pri konstruiranju prototipov, kjer se konstrukcija spreminja in s tem potrebujemo več izračunov. Z željo, po čim hitrejših izračunih so se ponovno začele uporabljati analitične metode ter kombinacije analitičnih metod z numeričnimi metodami. V tem članku bo predstavljen analitičen izračun magnetnega polja s pomočjo konformnih preslikav.
