Stepper motors are a subject that keeps recurring. This little circuit changes a clock signal (from a square wave generator) into signals with a 90-degree phase difference, which are required to drive ...

Discover how to build a simple electromagnetic motor and generator using everyday materials in this hands-on science ...

You can think of a generator as a motor that runs in reverse. Instead of supplying electricity to a stator to make the rotor spin, a generator is mechanically driven to make its rotor spin to supply ...

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 ...
