Abstract
An induction motor rotor unit adapted to support and rotate an X-ray target anode in an X-ray tube comprises a stacked array of very thin highly magnetic annular laminations on a cylindrical carrier. Gold plated copper conductor bars are placed in longitudinal coaxial slots in the circumference of the rotor. Gold plated end rings on the carrier abut each end of the stacked array and conductor bars. In a vacuum furnace the gold plating is caused to melt and diffuse into contiguous components to bond the rotor as an integral unit.
