Abstract

PURPOSE: To improve the speed characteristics by adopting a cage-type structure, in which a conductor of low electric resistance is burried in a core of a material having high mechanical strength.
CONSTITUTION: A cylindrical metal body 4 of high magnetic permeability, a core 2 having a plurality of conductor pieces 3 concentrically embedded in its outer periphery, end rings 5 electrically connecting the ends of the conductor pieces and shaft portions 6 for transmitting the rotation of the core to the outside are provided metallurgically integrally with one another. A high frequency motor using this rotor can withstand long use by high rpm operation at 30 thousand rpm or above.
