CONNECTOR ASSEMBLY Russian patent published in 2009 - IPC H02K7/118 F04D13/02 F16D3/02 

FIELD: motors and pumps; electric engineering.

SUBSTANCE: invention relates to electric engineering, particularly to connector assembly located between rotor of synchronous electric motor having permanent magnets and operating part. It is proposed to provide connector assembly (11) between rotor of synchronous electric motor having permanent magnets and operating part (17). The connector assembly consists of a driving element (22) being located eccentrically to rotor rotation axis and implemented as a one-piece element together with the first transmission component. The connector assembly includes also at least one driven element (24) being also located eccentrically to rotor rotation axis and implemented as a one-piece element together with the second transmission component being in kinematic sequence with the said first component. The driving (22) and driven (24) elements are placed in the sealed chamber (18) in different disjoint parallel planes. According to the invention, the above-mentioned driving (22) and driven (24) elements are functionally connected by kinematic connection (25). The axial spread of the said connection ensures its mating with the said parallel planes in the above-mentioned chamber (18). The said kinematic connection includes at least one elastic element (25a) squeesed in the said chamber (18) between bottom wall (19a) and locking sealed cover (19a).

EFFECT: lesser noise level during synchronous electric motor operation containing rotor with permanent magnets.
