Electric motors are easy to make; remember those experiments with wire-wrapped nails? But what’s easy to make is often hard to engineer, and making a motor that’s small, light, and powerful can be ...

Project Single Turbo has undergone extensive upgrades to its engine and supporting systems, most notably fuel and air delivery. To take control of these, we’ve installed a standalone ECU and upgraded ...

Earlier this month, we heard about the development partnership between the well-known Zero Motorcycles and Vancouver, BC-based Exro Technologies, which works on how to improve electric motors in ...

Reducing the weight of transportation like electric vehicles, drones, and spacecraft can lower energy consumption and improve battery efficiency. A key material that enables this lightweighting has ...

The linear voice coil motor (aka linear DC motor) is guided by a long-life plain bearing that can allow side loads up to 3 lb (13.5 N), while the precision ground 0.236-inch (6.0 mm) diameter shaft ...

The forefathers of speed could only dream of street cars that were both reliable and capable of 800 hp or more—funny thing is, these days it is commonplace. We can thank technology’s rapid advance ...

Machine and robot builders recognize linear motor benefits, but some are reluctant to integrate the components into design because of incomplete understanding of the technology. Here we overcome that ...

The car is not going to disappear anytime soon and neither is the combustion engine, despite the inevitable rise in fuel prices. We have said it before, electrical motors are an energy-efficient ...

This Design Idea further develops a previous one integrating a stepper-motor driver in a CPLD (Reference 1). However, this idea integrates not only the driver, but also a simple one-axis stepper-motor ...

Despite the best efforts of the RepRap community over the last twenty years, self-replicating 3D printers have remained a stubbornly elusive goal, largely due to the difficulty of printing electronics ...
