Abstract
A motor assembly includes a DC motor having a motor housing defining a stator, a rotor assembly supported for rotational movement with respect to the stator, and a shaft coupled to the rotor assembly for rotation about an axis of rotation A. The assembly includes a supporting structure carrying the motor and decoupling structure . The decoupling structure mounts the motor housing to the supporting structure in a manner to provide a certain natural frequency of the motor in torsion around the axis of rotation A of the shaft while providing natural frequencies higher than the certain natural frequency for degrees of freedom of the motor other than torsion. The assembly also includes pivot structure and , associated with the supporting structure and the motor defining a pivot between the motor and the supporting structure with a center of the pivot being aligned with the axis of rotation.
