ABSTRACT:
A structureborne vibration-compensated motor arrangement includes a pair of twin AC motors supported by a rotatable shaft structure and a stationary outer housing. Each motor includes an annular stator core structure and an annular rotor field structure. The stator core structure is mounted by an annular stator support member which, in turn, is stationarily supported by the outer housing. The rotor field structure is mounted by an annular rotor support member in spaced relation, either axially or radially, from stator core structure. The rotor support member, in turn, is mounted to the rotatable shaft structure for rotation therewith. The twin AC motors are mounted with the stator core structures located adjacent opposite sides of the stator support member and the rotor field structures located adjacent the respective stator core structures opposite from the stator support member such that the twin AC motors are arranged back-to-back as mirror images of one another for cancelling out axial and radial vibrations of the stator core and rotor field structures at respectively the outer housing an shaft structure. Additionally, the respective stator and rotor support members are mounted by yieldably resilient members which isolate torsional vibration of the stator core and rotor field structures respectively from the other housing and shaft structure.
