Abstract
PURPOSE: To prevent a circular vibration of a laminated core and a stator frame and realize an AC motor with low noise by mounting a parallel rib and a nonparallel rib to a rotor shaft alternately to a stator frame.
CONSTITUTION: Ribs A-F, parallel to a rotor shaft and nonparallel, which fix a laminated core 2 of a stator to a stator frame 8 are arranged alternately. With this construction, generation of the circular vibration is surpressed because each phase of circular vibrations generated between the end plate M and the other end plate N of a motor is different each other, and a motor with low vibration noise is realized.
