Abstract
A magnet machine includes a magnet rotor. The rotor includes a sleeve and a magnet. The magnet is positioned within the sleeve. A highly electrically conductive, nonmagnetic shield surrounds the magnet. The shield reduces rotor eddy current losses and lowers rotor operating temperature, thereby improving efficiency of the machine.
