1. A motor assembly comprising:

  • a DC motor including;

    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 supporting structure carrying the motor;

    decoupling structure mounting the motor housing to the supporting structure in a manner to provide a predetermined natural frequency of the motor in torsion around the axis of rotation of the shaft while providing natural frequencies higher than the predetermined natural frequency of the motor other than torsion, and pivot structure, associated with the supporting structure and the motor, defining a pivot permitting pivoting of the motor with respect to the supporting structure, with a center of the pivot being aligned with the axis of rotation.
