Product overview
V-827 direct drive linear stages are designed for high load, high throughput applications that also require long life, and high reliability.
V-827 direct drive stages offer superior straightness and flatness compared to similar motorized linear stages on the market. With a powerful, non-cogging, direct drive motor, the V-827 performs well in production environments.
The models with absolute encoder offer a resolution of 1 nm as well as a safe and efficient start that requires no initialization or referencing. The ultra-precision recirculating ball bearings are intended to be maintenance-free for the life of the stage.
Optional debris protection
The V-827 linear stage is also available with side seals for protection from debris, making it ideal for laser processing and similar applications. The V-827 is designed for XY mounting and can be configured accordingly at the factory.
Three-phase motors for higher dynamics and friction-free, maintenance-free operation
The three-phase linear motors of the V-827 linear stage family transmit the drive force directly to the motion platform without friction. This eliminates backlash and mechanical play that can result from mechanical components like gears and leadscrews in the drivetrain. These motors, which are ideal for high-velocity and high-acceleration applications, feature a friction-free and maintenance-free design that ensures a long service life in demanding 24/7 operation. Using the controller settings for current limitation, the motor can be easily disabled to prevent potential damage to the stage or application.
Recirculating ball bearings for industrial and automation applications
Recirculating ball bearings are well established in industrial automation environments and are known for their load capacity, reliability, and robustness. They provide a high level of smoothness, straightness, and flatness. The high load capacity of 150 kg guarantees long bearing lifetime.
Models with incremental or absolute encoder
V-827 direct drive stages are equipped with linear encoders that measure positions with maximum accuracy directly on the motion platform. Compared to indirect measuring methods, this improves linearity and ensures insensitivity to mechanical play and elastic deformation. Incremental encoders require a home signal to initiate. In contrast, absolute-measuring encoders provide explicit position information, enabling immediate determination of the position. This eliminates the need for referencing during switch-on, enhancing both efficiency and safety during operation.
Selection of the right precision linear stage and controller
Selecting the right linear stage is pivotal for optimal performance in high-precision positioning, motion and automation applications. Factors such as resolution, load capacity, guiding accuracy, and repeatability must be considered. The V-827 linear stage family offers particularly high geometric accuracy (flatness, straightness, pitch, and yaw) as well as very good bidirectional repeatability (150 nm) in a compact housing. With their highly dynamic properties, featuring 1 G acceleration and 2 m/s velocity, these precise motorized stages are ideal for the automation of highly accurate positioning tasks required for laser processing, inspection, and mass production of precision devices.
In combination with PI's A-8xx series motion controllers, these stages achieve unparalleled motion performance. The EtherCAT®-based A-8xx controllers offer a high degree of flexibility and facilitate the seamless integration of EtherCAT®-compatible devices from other manufacturers. Advanced algorithms in the A-8xx series motion controllers such as PILOT, enable higher dynamics with reduced motor currents and thus effectively increase the motor’s force constant.

Note on velocity and acceleration: It can be limited by payload, controller, or drive performance.
Note on linear and rotational crosstalk: Depending on the quality of the surface, the payload, the orientation and the forces acting on the stage from the outside. Please contact PI for application-specific parameters. The specified values are static (no rotary motion during measuring) and without load.
Note on positioning accuracy: With guiding error compensation. The specified values are based on error compensation controlled by the controller. The positioner must be ordered with a controller from PI to reach these values. Accuracy values assume short time duration and do not consider the long-term effects of thermal drift on the stage.
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.
