ROTATOR OF ULTRA HIGH-SPEED INDUCTION MOTOR

摘要

PURPOSE: A rotator of a ultra high-speed induction motor is provided to be capable of preventing deformation or a breakdown of parts by supporting a centrifugal force when rotating at a high speed. CONSTITUTION: A rotator(310) has a circular bar body(311), a shaft insertion hole(312), a plurality of penetration holes(313), and ring insertion grooves(314). The circular bar body(311) is formed by processing an iron core having a predetermined length, and the shaft insertion hole(312) is formed in the circular bar body(311) so as for a shaft to be inserted. The penetration holes(313) are placed at a circumference of the shaft insertion hole(312), and the ring insertion grooves(314) are formed at both sides of the circular bar body(311). Short rings(330) are inserted in the ring insertion grooves(314) respectively, and are joined with a plurality of fixing bars(320).
