To fully appreciate the chief advantages of linear motors, it is helpful to compare them to ballscrews, another high-precision rotary-to-linear transmission system. Although typical ballscrews are ...

Accuracy has two aspects. First is the accuracy of the actuator itself, determined by the moving element and its ability to travel in an ideal single-axis path or straight line. An inescapable truth: ...

There are a number of linear motion technologies availableto machine and device designers, each with advantages and disadvantages.Medical device design in particular, in which applications typically ...

Monitoring takes the form of sensors and intelligent devices connected to a digital processor. These monitored values are used for computing and then controlling some sort of real-world action. Many ...

Beckhoff’s AL8000 linear motors can now deliver greater accuracy and synchronization with the company’s new TwinCAT Cogging Compensation software. According to Beckhoff, this software enables linear ...

In the next few weeks, linear motors will face their ultimate litmus test. After years in the eye of a swirling technical storm, surrounded by doubters who say they're too expensive, supported by a ...

For manufacturers dealing with high precision, granite-based, multi-axis motion systems, two primary choices exist. One option involves designing a motion system where the granite base becomes an ...

Essentially, a guide wheel is a ball bearing that has a special shaped outer race. The inner and outer races of ball bearings are a framework with a groove for the balls to rest in. Burke explained ...

A new linear/rotary dual-motion actuator has been designed to provide incremental rotational and linear movement of the output shaft. The Size 14 actuator has two degrees of freedom of movement that ...

The accuracy of motion systems used in precision automation applications is significantly dependent on top-tier positioning stages and motion controllers. When designing a next-generation machine or ...
