An electronic linear servo motor can be used for applications where the infrastructure is not suitable for pneumatic systems [...] systems. A linear servo motor often has a threaded screw. In combination with an electric motor, this is flanged either directly or via a gearhead. The screw itself is either a lead or a ball screw, depending [...] These linear actuators are available with different screw lengths and diameters. Some linear servo motors also work without a lead screw. They are called linear DC servomotors. In this case, the linear ...
