Stepping Piezoelectric Actuators (SPA) are new long-stroke linear or rotating piezoelectric motors for micro/nano positioning applications benefiting from proven APA® heritage. They operate by accumulation of small steps. The motion can be either linear (LSPA motors) or rotary (RSPA motors). The motors can be supplied with the dedicated controller SPC45 or with standard Linear Amplifiers CA45 or LA75.
