The V-857 is a heavy-duty, highly dynamic linear stage designed for industrial use. Its design is continually geared to harsh industrial settings, with high rigidity and the use of high-quality components, such as recirculating ball bearing guides, three-phase linear motors, and incremental or absolute linear encoders.
Features include:
- Long travel ranges (to 800 mm) with narrow profile (132 mm width)
- Highly dynamic, maintenance-free linear motor with velocities up to 5 m/s
- Permanent load capacity to 1000 N
- High-precision incremental or absolute linear encoder
- Sophisticated industrial design for a long lifetime
- Ideal for gantry systems

The encoders’ high resolution enables outstanding tracking performance, small tracking errors, and quick settling times. Connectors that are industry-compatible provide rapid and secure connectivity. With a triple M6 hole pattern, the alternative motion platform provides numerous assembly options.
Linear Motor With Direct Drive
Three-phase magnetic direct drives do not require mechanical components in the drivetrain; instead, the drive force is sent directly and without friction to the motion platform. The drives achieve tremendous velocities and accelerations.
Ironless motors are particularly well suited for precision positioning tasks because there is no undesired interaction with the permanent magnets. This enables smooth operation at low speeds while eliminating vibration at high velocities. Control behavior is nonlinear, and any position can be easily controlled. The drive force can be easily adjusted.
