The presented motor is a linear stepping motor so called Fine Stepping Piezo Actuator (FSPA) able to support large external force without losing its holding position whether powered or unpowered.
FSPA are based on inertial stepper piezo motors. They are composed of four main elements: an actuator, a lever arm, a mass and a clamp. The principle of such motors is simple and relies on stick-slip effect and dissymmetrical accelerations.
