Product Description
Figure 1: Different motor versions of the M-403 linear stage family with 100 mm
travel range (from left): M-403.4PD (DC-motor/Active Drive(TM)),
M-403.4DG (DC-motor/gearhead) and M-403.42S (stepper motor)
The optimum choice of high-value, low-cost components makes the M-403
family of linear stages very attractive and economical. These stages are
leadscrew-driven and provide a minimum incremental motion to 0.2 µm. The
precision-machined, high-density, stress-relieved aluminum base provides
exceptional stability with minimum weight. M-403 are available in 5 lengths
providing travel ranges from 25 to 200 mm.
High-Load and Maintenance-Free
All models are equipped with high-precision linear guiding rails and
recirculating ball bearings. The recirculating ball bearings are maintenance
free and immune to cage migration. The choice of components and careful
mounting guarantees high load capacity, longer lifetime and high guiding
accuracy.
The stages can carry up to 20 kg and push/pull up to 50 N.
Three Motor Drive Options
M-403.xPD versions feature the high-performance ActiveDrive™ system.
The ActiveDrive™ design, developed by PI, features a high-efficiency PWM
(pulse width modulation) servo-amplifier mounted side-by-side with the DC
motor and offers several advantages:
■
Increased efficiency, by eliminating power losses between the
amplifier and motor
