MICRO MOTOR ROTOR SUPPORT

摘要

Disclosed is a micro motor rotor support, which comprises a support frame, a shaft sleeve and a fastening ring, said support frame comprising a top plate which has an accepting hole, said shaft sleeve being mounted in the accepting hole, said fastening ring being mounted on the shaft sleeve and fixed on the top plate and its opening having at least one inclined spring sheet formed on an inner edge thereof, said spring sheet contacting with and applying pressing force to an outer surface of said shaft sleeve. The outer surface of said shaft sleeve has at least one groove, and said fastening ring or top plate has at least one projection which is locked into the groove. In the present invention, the shaft sleeve can be prevented from rotating with the rotor effectively and can be adjusted freely to keep coaxial with the rotation axis of the rotor.
