The SCR Nano-positioning Series from Micromech offers the accuracy of piezo-driven stages with the speed and performance of servo stages.

Through the use of complex motion profiles, the SCR series produces accurate results with no loss in stability.

As in all linear-shaft-motor applications, a non-critical air gap produces an environment that is void of any variations in force.

With a simple, lightweight, compact shaft-type linear motor comprised of a magnet and a coil, large drive force is gained with an efficient and short coil length, allowing for high-speed, high-precision applications.

Because there is no friction, there is no sound or dust, making the motor maintenance free.

These stages also include an integrated cross-roller guide.

All the SCR stages can be supplied as an X-Y stage to insure true orthogonal orientation between the two axes.

The SCR-050 stage utilises a linear shaft motor, making it a compact, precise solution for small-scale stage applications.

The stage itself contains the cables within a stationary base and uses a moving magnet design.

With a built-in optical linear encoder that provides sub-micron resolution, the SCR-050 is a complete compact stage solution for small-scale precision movement.

Each SCR stage requires a servo driver to operate the stage.

Any two SCR stages will bolt directly together, forming a very stiff, compact X-Y assembly standard, without the need for adapter plates.

There are two models with travel/strokes of 20 or 40mm, accuracy of 2mm, maximum acceleration of 20 or 8m/s2, maximum velocity of 0.6 or 0.5m/s and a load capacity of 10kg.

The SCR-075 stage is a complete single-axis stage, integrating a slide guide, encoder and linear shaft motor.

It offers a range of advantages for applications requiring high performance and accuracy.

The linear motor is said to allow for higher resolution, speed and continuous force than the standard stepper or piezo servomotor.

The SCR-075 also uses a linear shaft motor, however the coil windings can be customised to a double, triple or quadruple winding.

There are three models in this range with a travel/strokes of 50, 100 or 150mm, accuracy of 3, 5 or 7mm, maximum acceleration of 25, 20 or 15m/s2, maximum velocity of 1.1, 1.4 or 1.5m/s and a load capacity of 45.5kg.

The SCR-100 stage has six travel/stroke lengths and three motor windings, and integrates a slide guide, encoder and linear shaft motor.

A range of options allows for a better match for stage applications needing sub-micron resolution that is free from motion errors.

The travel/strokes range from 50, 100, 150, 200, 250 up to 300mm, accuracy 3, 5, 7, 9, 11 and 12mm, a maximum acceleration of 2, 17, 12, 10, 8, 7 and 6m/s2, maximum velocity of 0.9, 1, 1.2, 1.2, 1.3 and 1.3m/s and a load capacity of 45.5kg.

The largest of the SCR stages, the SCR-150 stage has stroke lengths up to 300mm, while maintaining the high performance and accuracy of the smaller SCR stages.

Like the other three stages, the SCR 150 is a complete single-axis stage that integrates a slide guide, an encoder and a linear shaft motor.

The travel/strokes are 100, 150, 200, 250 and 300mm, accuracy 5, 7, 9, 11 and 12mm, maximum acceleration 17, 13, 11, 9 and 8 m/s2, maximum velocity 1.3, 1.3, 1.4, 1.5 and 1.5 m/s, and a load capacity of 45.5kg.
