Generator runners, in particular turbocharger runners, with superconducting pathogen development

摘要

Generator rotor, including an inner and an outer concentric rotor part having a non-drive side and enclosing a high vacuum space, a first and a second bearing disposed on the non-drive side, a hollow shaft end of the outer rotor part being supported in the first bearing, a journal of the inner rotor part being extended through the hollow shaft end and separately supported in the second bearing, a high-vacuum contactless liquid seal disposed between the hollow shaft end and the journal and having a sealing gap formed therebetween, a co-rotating sealing-liquid reservoir connected to the liquid seal, and magnetic field means for holding magnetic sealing liquid in the sealing gap.
