Compact Industrial Design for Applications with Low Power Requirements

For industrial applications, the V-855 is a heavy-duty and highly dynamic linear stage. Its design has been constantly geared to challenging industrial conditions. It is specified by high stiffness and the usage of high-quality components: a 3-phase linear motor, recirculating ball bearing guides, and incremental or absolute linear encoder.

The high resolution of the encoders enables outstanding tracking performance, short settling times, and small tracking errors. The optional motion platform provides flexible assembly options with a triple M6 hole pattern.

Linear Motor with Direct Drive

The availability of 3-phase magnetic direct drives does not use the drivetrain's mechanical components. They transmit the drive force to the motion platform instantly and without friction. The drives reach high accelerations and velocities.

Ironless motors are ideal for positioning tasks with the most significant demands on accuracy because there is no unwanted interaction with the permanent magnets.

This enables smooth running even at the lowest velocities, and simultaneously, there is no vibration at high velocities. Nonlinearity in control behavior has been prevented, and it is possible to control any position efficiently. The drive force could be set freely.

Options
