DC motors come in many forms, but they all have the same job: turning electrical energy (DC) into mechanical energy. Although DC motors have a common operating principle, many applications—including ...

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 ...

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 ...

Finding just the right off-the-shelf part to complete a project is a satisfying experience – buy it, bolt it on, get on with business. Things don’t always work out so easily, though, which often ...

Researchers have succeeded in constructing the coil of an electric motor using only carbon nanotubes without any metals, and realizing it to the point where it can actually run. (Nanowerk News) ...
