Abstract

Oppfinnelsen gjelder beskyttelse, montering og fastholding av magnetiske poler bestående av permanentmagneter i store elektriske maskiner. Hver pol omfatter en eller flere permanentmagnet polelementer. Polelementet er tiltenkt å monteres på rotoråket til en elektrisk maskin og består av minst en permanentmagnet, beskyttende innkapsling som omgir magneten(e) fra alle sider bortsett fra bunnsiden, og en baseplate på hvilken nevnte minst en magnet er festet, for fiksering av polelementet til rotoråket. Både baseplaten og den beskyttende innkapslingen er laget av det samme materialet eller materialer som er kompatible slik at ingen korrosjon oppstår ved sammenføyningen. Baseplaten og den beskyttende innkapslingen er sveiset sammen.The invention relates to the protection, mounting and holding of magnetic poles consisting of permanent magnets in large electrical machines. Each pole comprises one or more permanent magnet pole elements. The pole element is intended to be mounted on the rotor yoke of an electric machine and consists of at least one permanent magnet, protective enclosure surrounding the magnet (s) from all sides except the bottom side, and a base plate on which said at least one magnet is attached, for fixing the pole element to rotoråket. Both the base plate and the protective enclosure are made of the same material or materials that are compatible so that no corrosion occurs during joining. The base plate and the protective housing are welded together.
