Radford, Va. – Nippon Pulse America’s new SCR100 stage is an ultra high precision, compact single axis stage that integrates a slide guide, encoder, and Linear Shaft Motor. It offers a wide range of advantages for ultra high performance and accuracy applications. The Linear Shaft Motor is a coreless direct drive linear motor which has zero cogging, allowing for higher resolution, speed, and continuous force than standard stepper motors and piezo servomotors.
The SCR100 stage is a moving magnet design, which locates all cables and connectors in the stationary base. The absence of any moving cable means a clean and compact design and eliminates motion errors due to cable forces. The precision ground cross roller way provides high stiffness and smooth motion. Together they are capable of supporting higher torque levels due to offset loads with travels from 50mm to 300mm. The non-contact Linear Shaft Motor and optical linear encoders are self-contained inside the stage, making it a low-profile compact solution. The built-in non-contact optical linear encoder is available with resolutions from 1 micron to 10 nm with digital output. The sub-micron resolution results in a high accuracy stage, which is laser tested for optimum performance.
The SCR100 stage has the added benefit that any standard digital servo driver can drive the SCR100 stage. Any two SCR stages will bolt directly together to form a very stiff, compact X-Y stage. Two SCR stages can be supplied compounded as an X-Y stage to insure true orthogonal orientation.
