Industrial design for high performance and high load
The V-857 is a heavy-duty and highly dynamic linear stage for industrial applications. Its design is consistently geared to demanding industrial conditions and it is characterized by high stiffness and the use of high-quality components: recirculating ball bearing guides, 3-phase linear motor, incremental or absolute linear encoder. The high resolution of the encoders allows for an excellent tracking performance, small tracking errors, and fast settling times. Industry-compatible connectors offer a fast and secure connectivity. The optional motion platform offers versatile assembly options with a triple M6 hole pattern.
Linear motor with direct drive
3-phase magnetic direct drives do not use mechanical components in the drivetrain, but transmit the drive force to the motion platform directly and without friction. The drives reach high velocities and accelerations. Ironless motors are particularly suitable for positioning tasks with the highest demands on precision because there is no undesirable interaction with the permanent magnets. This allows smooth running even at the lowest velocities and at the same time, there is no vibration at high velocities. Nonlinearity in control behavior is avoided and any position can be controlled easily. The drive force can be set freely.
