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 ...

While renewable energy offers many opportunities for decentralizing energy production, it can sometimes feel that doing so on a truly local level remains unachievable with increasingly large ...

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 ...

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 scenario goes something like this. Our LS3 used to rev freely and make power all the way up through 6,800 rpm, but now it struggles to get to 6,000 and power is definitely down. After a thorough ...

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) ...
