Any project that contains something called a “flux modulator” instantly commands our attention. And while we’re pretty sure that [Retsetman] didn’t invent it after hitting his head on the toilet, this ...

What if the future of precision mechanics didn’t rely on massive manufacturing plants or multimillion-dollar R&D budgets, but instead emerged from a 3D printer on a hobbyist’s workbench? That’s ...

Gearboxes in general are a result of over 80 years of accumulated engineering knowledge. So why do gearboxes for wind turbines sometimes fail after seven to 11 years — way less than the anticipated 20 ...

The choice between helical and spur gears in gearboxes may seem straightforward. Go with helical gears if you want the gearbox to run as smoothly and quietly as possible. Choose spur gears when you ...

Invention of the gear-hobbing process about 150 years ago revolutionized not only gear fabrication, but also gear design. Basically, a hob or shaper cutter traverses the gear blank to generate teeth.

Drive System Design (DSD) and Alvier Mechatronics have teamed up to create a development platform for electric vehicle drives. “The project leverages DSD’s expertise in rapid development engineering ...

Sometimes a gearbox problem can be easily identified by the sound it makes during operation. Conversely, other situations exist for which “normal sounding” and “abnormal sounding” are simply too ...
