ABSTRACT:
A moving body (10) is composed of a main body (11), piezoelectric elements (13), (13′) secured to the sides of the main body in the traveling direction thereof, and coils (12), (12′) secured to the piezoelectric elements (13), (13′). A magnet is disposed on a guide rail and the coils (12), (12′) are energized, and whereby the moving body (10) can be moved a long distance at high velocity by a magnetic type linear motor system. Further, the coils (12), (12′) are energized, the main body (11) is pressed against the guide rail on which the magnet is mounted by the magnetic force that is generated by the energization of the coils (12), (12′) and the piezoelectric elements (13), (13′) are extended and contracted by a voltage applied thereto, thereby the moving body (10) is impact driven. With this operation, the moving body can be micro driven at a pinpoint accuracy. With above arrangement, there can be provided an actuator that can make both a high velocity movement of a large stroke and a micro movement of a pinpoint accuracy.
