Abstract
A vacuum centrifuge has a cylindrical centrifuge housing forming a vacuum chamber and a cylindrical centrifuge pot is coaxial with the vacuum chamber. An elongated hollow shaft extends externally and coaxially from the cylindrical centrifuge pot and forms a passage for an elongated thread carrier tube extending into the pot. At least one magnetic bearing and a motor surround the elongated hollow shaft. An annular wall connects a terminal end of the elongated hollow shaft to the cylindrical centrifuge pot and forms a boundary surface within the vacuum chamber in which the centrifuge pot is located.
