ABSTRACT:
An induction motor rotor particularly for x-ray tube applications comprises a series of hollow cylinders fitting concentrically on each other and on a motor shaft. The first cylinder is a highly heat resistant and electrically insulating material. The next cylinder is a highly magnetic material cylinder fitting on the first cylinder. The next and outermost cylinder is an electrically conductive material providing the armature conductor of the induction motor rotor.
