Beckhoff optimizes linear motion with machine learning solution that eliminates cogging
The highly dynamic AL8000 linear motors from Beckhoff now meet even greater requirements for accuracy and synchronization with the new TwinCAT Cogging Compensation software. This makes the linear motors particularly suitable for high-precision applications such as milling machines or laser cutting machines. The cogging compensation software makes use of machine learning, which is seamlessly integrated […]
How to account for rack and pinion inertia during system design
Rack and pinion drives are often used in applications that require stroke lengths beyond the practical limits of ball screws and thrust forces that exceed the capabilities of belt drives. And in some applications, rack and pinion systems can also provide lower total inertia than a suitable ball screw or belt drive alternative, which can […]
How is an LVDT similar to a resolver?
Both LVDTs (linear variable differential transformers) and resolvers are measuring devices that convert displacement into an electrical signal. As its name implies, an LVDT is used for linear measurement, while a resolver is used to measure rotary, or angular, displacement. In terms of construction and operation, the most significant similarity between an LVDT and a […]
5-axis stage with closed-loop motors for precision and alignment
PI (Physik Instrumente) LP offers a compact 5-axis stage for precision alignment and positioning required in fields such as fiber-optics and photonics. The modular, 5DOF motorized stage consists of a 3-axis linear module and two goniometers. A multi-axis controller and software with automated alignment functionality is also available. Sub-micron precision is guaranteed by highly accurate […]
How to calculate the effect of preload on ball screw axial deflection
In a recent post, we looked at the methods for inducing preload in a ball screw assembly and the effects it has on performance. One of those effects is that preload reduces axial deflection (displacement) and increases rigidity. But preload also increases the applied load on the screw assembly and reduces life. To determine the […]
