Abstract: Rotating machines and rotors therefor are disclosed. The bearings may be magnetic bearings configured to magnetically levitate the rotor. The rotors may include a hollow fiber-reinforced composite shaft and a magnetic bearing rotor core disposed on the shaft and configured for use with the magnetic bearing. In some examples, the rotating machines may be electrical machines.

Abstract: Rotors for electrical machines and methods of fabricating the same are disclosed. Electrical machine rotors may include a hollow non-magnetic shaft, an active region, and a plurality of coolant passages extending within the active region. The hollow non-magnetic shaft may extend along an axis and have an exterior surface that defines a shaft space extending along the axis. At least a portion of the active region may be disposed within the shaft space.
