Abstract
Foreliggende oppfinnelse tilveiebringer en elektrisk maskin (1) med redusert cogging. Magnetpolene (3) til den elektriske maskinen innbefattes av minst to separate grupper av minst to omkretsmessig tilstøtende magnetpoler. En av de omkretsmessige ytre magnetpoler (3) i en av gruppene av magnetpoler er definert som å være i sin referanseposisjon. Referanseposisjonen til hver annen magnetpol (3) er definert som den posisjonen hver annen magnetpol vil oppta hvis alle magnetpolene var likt omkretsmessig anbrakt med mellomrom rundt det første eller andre legemet og den ene omkretsmessige ytre polen var i sin referanseposisjon. Minst en av de omkretsmessige ytre magnetpolene (3) i hver gruppe er plassert i sin referanseposisjon. Minst en magnetpol (3) i hver gruppe er en forskjøvet magnetpol og befinner seg i en posisjon som er forskyvbar fra dens referanseposisjon med en størrelse som ikke er lik et heltallsmultippel av viklingsslissenes referansevinkelsprang. Magnetpolenes (3) forskyvning tilveiebringer en uttalt reduksjon i cogging.
