Rotating electric motors such as DC or stepper motors are used in connection with screw or worm drives. Stepper motor systems with high-resolution encoders can perform minimum incremental motions of 10 nm with high reliability and repeatability.

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.

At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.

PIMag® 6-D is an electromagnetic positioning system in which the passive platform levitates on a magnetic field and is actively guided by it.

In the hybrid concept, the DC servo motor (large travel ranges) and the piezo drive (nanometer accuracy) are combined with one another.

In particular in terms of wear and dynamics, magnetic direct drives offer advantages compared to common spindle-based technologies.

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.
