How does temperature affect ball screw assemblies?

Reprint of Danielle Collins post, Linear Motion Tips, on Friday, December 11, 2015

As an integral part of industrial machines and processes, ball screw assemblies often operate in environments with elevated temperatures. Heat can be generated by other mechanical and electrical components in the machine, and in some cases, is a byproduct of the process itself. And, like other motion products with sliding or rolling friction, ball screws generate heat of their own as they run. This heat, and especially the change in temperature that occurs over time, can have a detrimental influence on the screw’s function. But there are ways to mitigate heat and reduce its effect on life and accuracy.

Operating temperature recommendations for ball screw assemblies vary among manufacturers, but the typical upper limit for the most common ball screws is 80° C for short, instantaneous exposure, and 50° C for continuous duty. For standard annealed screws, a temperature over 100° C can cause a decrease in tensile strength and should be discussed with the manufacturer.

Three critical factors for servo motor sizing

Reprint of December 30, 2015 Linear Motion Tips article from Design World


Servo motor sizing is often done with the help of a manufacturer’s sizing program, but it’s important to understand the three most critical factors—speed, torque, and inertia—to ensure you select the best-fit motor for the application.

Selecting the right servo motor for a linear motion system is a complex task, beginning with initial assumptions and component selections, which must be checked through a series of calculations and, in most cases, repeated over several iterations until a suitable combination of motor and mechanics is found. Most motor manufacturers offer online sizing tools that make the process easier, ensure that the best components are selected, and help preserve the design engineer’s sanity. But as a designer, or even an end user, it’s important to have an understanding of the three critical parameters of servo motor sizing: inertia, speed, and torque.

Theory, Application & Operation of Frameless Motor Technology. Live Webinar.

February 23, 2016  11:00 AM ET

Register to watch the webinar on or after February 23.

For many years there seems to have been an engineering mystique surrounding the integration of frameless motor part sets into high performance machine design. This has kept many machine design engineers from jumping in to embed these power and torque dense motor types into their applications.

This webinar will focus on the integration of frameless motors into practical machine design challenges. We will touch on the background and use of embedded motor components, typical application overview, performance improvement expectations, typical design and installation best practices, drive amplifier and feedback considerations, and machine system thermal concerns.

We will also review some basic tools available to help design engineers optimize frameless motor performance in customer machine applications.

Ethernet or EtherCAT for Motion Control Webinar: Choosing the Right Network for Your Applications

JANUARY 26, 2016  |  11:00 AM ET

With the increasing presence of EtherCAT in the motion control industry, choosing between EtherCAT and Ethernet is becoming an increasingly important question. This presentation will cover the technical differences between both methods and provide advice on how to choose between them based on application requirements.  Strengths and weakness of both Ethernet and EtherCAT will be discussed including development time, ease of use, cost, and complexity.

Additionally, Galil’s DMC-500×0 EtherCAT Master and DMC-40×0 Ethernet controller will be reviewed with regards to the capabilities and advantages they can offer.  This presentation is geared towards system developers looking to understand the differences, costs, and capabilities of both Ethernet and EtherCAT.

Can’t make the live webinar?  Register today and we will send you a recorded copy after the live presentation.

New Webinar: ‘How Magnetic Sensing Technologies are Changing How You Use Rotary Encoders’

YouTube 39min Webinar

For year’s controls and systems engineers have had to balance the robustness of magnetic encoders with the performance of optical encoders.  However, this is no longer the case due to recent advances in magnetic sensing technologies.  Breakthroughs in microprocessing and signal filtering have resulted in new magnetic encoders that can rival the performance of optical sensors while being more robust and compact. Learn how to select an encoder for a given application and what the future holds.

Four Critical Questions for Cryogenic Motors and Their Applications

White Paper by Richard Halstead, president, Empire Magnetics Inc.

Empire Magnetics Cryogenic motor snippetTypically people don’t think about motors  or motion control in cryogenic situations,  but there are many situations that call  for motion at very low temperatures.  For  example, fuel valves that carry liquefied
gases, such as hydrogen and oxygen, for  rocket engines must have the ability to not  only open and close but also to adjust flow  rates at low temperatures.  Quality control engineers need to be able to replicate the environment of space in order to ensure that equipment designed for satellites will function reliably before they go into space.  Likewise, observatories using supercooled equipment to capture spectral images of stars need scanners and other equipment with sophisticated control systems that, at least in part, operate in cryogenic conditions…
