PI (Physik Instrumente) has introduced the M-122 palm-top-sized precision translation stage that combines compact dimensions, high dynamics and speed and high accuracy at a competitive price
The M-122 features a space saving, folded drive train with the servo motor and drive screw side by side.
Equipped with a non-contacting optical linear encoder and a preloaded, precision-ground, ball-screw, these stages can provide much higher accuracy, better repeatability and dynamic performance than conventional stepper motor stages or rotary encoder-equipped servo motor stages.
Features and benefits of the M-122 include:.
- Long Travel Range: 1 Inch (25 mm).
- Compact: Smallest ballscrew driven stage with linear encoder: 60x86x20mm.
- High dynamics and speed: Servo motor direct drive provides up to 20mm/s, better dynamic response than stepper motor drives.
- Precise: 0.1 micron resolution optical linear encoder for higher linearity and repeatability.
- Cross-roller bearings for high load capacity and excellent guiding accuracy.
- Long life and low maintenance: Recirculating ball screw provides high speed and long lifetime.
M-122 stages can be driven with the low cost, networkable, C-862 Mercury servo motor controller/driver.
For multiaxis applications, the C-843 PC Board is available.
M-122 stages can be combined to compact XY and XYZ systems.
Owing to its low-friction, the backlash-free ball screw yields significantly higher mechanical efficiency than leadscrews, and allows maintenance-free, high duty-cycle operation at high velocities up to 20mm/s.
Typical applications include: Metrology, quality assurance, testing equipment, micromachining, photonics packaging, fibre positioning.
