Induction Motor for Superconducting Synchronous/Asynchronous Motor.
Abstract
The patent relates to an induction motor structure for use on the outside of a superconducting rotor comprising a cylindrical shell of solid and laminated, magnetic iron with squirrel cage windings embedded in the outer circumference of said shell. The sections of the shell between the superconducting windings of the rotor are solid magnetic iron. The sections of the shell over the superconducting windings are made of laminations of magnetic iron. These laminations are parallel to the axis of the machine and are divided in halves with the laminations in each half oriented in diagonal opposition so that the intersection of the laminations form a V. This structure presents a relatively high reluctance to leakage flux from the superconducting windings in the syncronous operating mode, while presenting a low reluctance path to the stator flux during asynchronous operation.
