How to Design a Custom Brushless PM Motor

[ Design World Exchange Featured Editorial - Join the Discussion ]



When off-the-shelf motors can’t meet the specs, you might have to go custom, but it’s not as bad as it used to be.



Pilotless aircraft engine controls and avionics have joined with the “X-box” and miniature motor-control devices and graphics displays to create a new generation aircraft designated the Unmanned Aerial Vehicle or UAV. Aerial vehicle names like… Continue

Load Control via Bellows Couplings

[ Design World Exchange Featured Editorial - Join the Discussion ]



For years, bellows couplings have been a mainstay for efficient motion systems because they offer high torsional stiffness, low moment of inertia, and minimal restoring forces under misalignment. They may help maintain tight control over loads, which is especially critical when considering that the flexible coupling often represents the point of least stiffness in an electromechanical system. In this… Continue

3D CAD and Model-Centric Design

Design World Open Discussion Feature:



A landmark study from Aberdeen Group reports that 85% of the current CAD users still primarily use 2D drafting. This astonishing statistic means that most companies use CAD software as a drafting tool to create orthographic views to represent 3D objects.



Drawings alone are no longer adequate to capture the design innovations that engineers create. So why are we still using an approach that is open to interpretation… Continue

Elektro the Westinghouse Robot

I came across a scan I had of a robot design / concept from what I imagined was from the 50's - and figured it was a joke of sorts, or wacky concept. The engineers even ensured that the robot had a bellows apparatus so the humanoid robot could smoke - a sure sign of the times.



It turns out a… Continue

SLA Makes WALL-E Look Battered

The real life WALL-E that visits newsrooms, tradeshows, and media had to look like the animated WALL-E from the movie. It takes a lot of care to make WALL-E look old and battered.







Because the animated WALL-E from the movie has been around for a long time, his digital body had been weather-worn and beat up by the work he does – compacting trash and stacking it neatly. Computer animation allowed animators to create the look and feel of a well-worn WALL-E, but… Continue

Infrastructure Software Simplifies Factory Design

V8i, said to be the most comprehensive infrastructure software ever assembled in a single release was introduced by Bentley Systems. Although it includes products for all infrastructure design needs from wind power to bridges and dams, we’re particularly impressed with the software tools included for designing factories and manufacturing facilities. The V8i portfolio leverages and extends core capabilities of its new interoperability platform to provide the breadth and depth of… Continue

Wireless Really?

Reading this article: "The Festo sensor/actuator level now features one of the fastest and most reliable short-range wireless communications systems available. WISA-COM, the wireless communications standard from ABB, will in future facilitate wear-free signal transmission to I/O modules. This will increase machine availability and reduce engineering and assembly costs."



I was involved with motion networks a few years ago (going from ±10V to 100BaseT) and although wiring… Continue

Fiber Helps Energy-Generating Aerial Wind Turbine Lift Off

Kuraray America’s Vectran® fiber is used in a cable tether that suspends a new type of alternative energy device – a lighter-than-air tethered wind turbine that rotates about a a horizontal axis in response to wind, generating electrical energy.





Vectran is the core of a braided cable tether that is wrapped with copper to carry electrical currents. The tether is part of a connection system that hooks the generators on each side of the… Continue

Green TIPS

Every month Design World puts together GreenTIPS - a digital edition covering green practices related to design engineering. At DW we define green engineering as the design, commercialization and use of processes and products that are feasible and economical while minimizing:



• Generation of pollution at the source.

• Risk to human health and the environment.



Green Engineering can transform existing engineering disciplines and practices to those that lead to… Continue

BattleBots, Blendo and DualVee

Great story here- excerpt on the development of Blendo.



Enter Jamie Hyneman, founder of San Francisco visual effects shop M5 Industries and host of the Discovery Channel’s MythBusters, who discovered DualVee bearings at a surplus store years before his television debut.



“I ran across them and thought they had an unusual design that was really quite elegant,” Hyneman says of DualVee. “I looked at the grooved edge and thought, ‘Hmm,… Continue
