Title (EN) A SLIP RING FROM DIFFERENT MATERIALS
(FR) BAGUE COLLECTRICE COMPOSÉE DE DIVERS MATÉRIAUX
Abstract:
(EN) The present disclosure relates to a slip ring for an electric machine to transfer current from a current source to a rotor of an electric machine. It is an object of the invention to provide a slip ring with improved properties against the state of the art. Disclosed is a slip ring for an electric machine with a cylindrical body made out of a first material with an electrical conductivity in the range of 1*106 S/m to 100*106 S/m and a thermal conductivity in the range of 50 W/mK to 500 W/mK, with a cover out of a second material which encompasses the cylindrical body.
(FR) La présente invention concerne une bague collectrice destinée à une machine électrique pour transférer le courant provenant d'une source de courant à un rotor d'une machine électrique. La bague collectrice selon l'invention présente des propriétés améliorées en comparaison à l'état de la technique. Ladite bague collectrice destinée à une machine électrique comporte un corps cylindrique composé d'un premier matériau possédant une conductivité électrique dans la plage de 1*106 S/m à 100*106 S/m et une conductivité thermique dans la plage de 50 W/mK à 500 W/mK, et un couvercle composé d'un second matériau englobant le corps cylindrique.
