Webdrive voltage: 290 V drive voltage: 60 V Figure 5. Maximum velocity of SDA under various driving conditions. 5. Scratch drive actuator force analysis Forces generated by SDAs have been measured [9] by a technique using a buckling beam. The SDA is connected to a beam that buckles out of the plane of the silicon surface as the SDA exerts a force. WebDuff-Norton and Pfaff-silberblau Screw Jacks (mechanical actuators) are versatile and robust, ideal for heavy duty applications. Easily customized modular design for unlimited …
