ABSTRACT:
This invention relates to a motor and a motor apparatus and is so constructed that end rings and bars composing a squirrel cage rotor of the motor are formed in a hollow or grooved shape and superconductive materials are filled within said end rings and bars to form looped circuits, which are symmetrical relative to a center line of a field, of a number equal to a number of poles, by the superconductive materials filled in each two bars and both end rings, so that the motor exhibits starting characteristics similar to those in an induction motor using a squirrel cage rotor composed of usual conductors by starting in an atmosphere of room temperature, and the operational characteristics as a very highly efficient synchronous motor by cooling the rotor to a critical temperature or less of the superconductive material after starting a permanent direct current flows through field windings composed of the superconductive materials.
