Compact Linear Stages with Piezomotor Drives

Piezomotors combine the characteristics of high stiffness and position resolution typical of piezoceramic actuators with theoretically unlimited travel ranges. They can replace traditional motor-spindle combinations or direct magnetic drives used in the application. This is of particular interest when the application offers only a small installation space or requires high resolution. Depending on the task at hand, PI has developed several piezomotor technologies offering, for example, high velocities of up to 500 mm/s or high forces of up to 800 N.
