Abstract
A direct drive system for a high speed ultracentrifuge. The drive spindle assembly is removable through the rotor chamber without disturbing any vacuum seals that are present to isolate the requisite vacuum environment in the rotor chamber for high speed rotation. All of the high speed bearings are connected to the spindle assembly for removal as a unit. An induction motor provides the direct drive with the motor armature mounted on the drive spindle assembly.
