摘要： A motion control system that includes a base, a stage supported by the base and movable with respect to the base, and a motor coupled to the base and operable to move the stage. The motor includes a mounting base arranged to connect the motor to the base, a friction pad engageable with the stage, and a coupling portion including a first end connected to the mounting base and a second end. The friction pad is connected to the coupling portion between the first end and the second end. A piezoelectric element is disposed between the mounting base and the second end and is operable in response to an electrical signal to move the friction pad and the stage. A mounting screw is accessible from an exterior of the base and engages the coupling portion. The mounting screw is the sole attachment mechanism between the motor and the base.
