Open-Loop DC Motor Actuators

 

The SGCD low-cost DC motor actuators are open-loop and intended for simple automated or remote movement of linear stages or other precision positioners.   Even with their amazingly small diameter (about the size of a felt-tipped highlighter) they have thrust load capacities up to 7kgf.

 Stepper Motor Actuators

 

Our SGSP stepper motor actuators are also open-loop but are fitted with precise origin/ limit sensors which provide repeatability to 3µm. They are deceptively compact, having a cross-section of 20X20 mm.

Encoded DC Motor Actuator

 

The RMH actuator provides excellent 2µm repeatability owing to its built-in rotary encoder.  A dedicated 2-axis controller is available to provide either computer or joystick control of the actuators.

 Piezomotor Actuators

 

Our PDM piezomotor actuators are compact and provide extremely high-resolution incremental movement, as low as 20nm.  PDM actuators are also available in a vacuum-compatible version.
