High Precision, Direct Drive Linear Servo Systems

The Linearserv is a direct drive linear actuator servo systems. Each complete system consists of a brushless linear servo motor, microprocessor-based servo drive with integrated power supply, precision linear guide with rugged square rail bearings and an optical linear encoder for servo feedback.

The primary benefit of the Linearserv system is the simplicity of the design. The Linearserv provides precise linear motion without belts and pulleys, gearboxes, leadscrews or other rotary-to-linear conversion devices that introduce inaccuracies and system complexities.

The performance difference between the LM1000 and LM5000 Series are maximum force, positional accuracy, maximum speed, encoder resolution and repeatability.
