ABSTRACT:
A piezoelectric moving linear motor consists of three piezoelectric actuators which are controlled relative to each other. One piezoelectric actuators causes two blocks to move away from each other in opposition to a spring force. The other two piezoelectric actuators selectively clamp a block to a guide shaft. By cyclically controlling the actuation of the three piezoelectric actuators, the motor is able to move the blocks axially along the guide shaft. Preferably, a vehicle component such as a window is fixed to one block and is caused to move along the guide shaft.
