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

[Robert Murray-Smith] doesn’t like the price of inverters to convert DC to AC. That led him to build a dynamotor, or what is sometimes called a motor-generator set. These devices are just DC motors ...

The 34-Year Experiment That Turned Plastic Tubes Into A Living “Species” Border Patrol is monitoring US drivers and detaining those with 'suspicious' travel patterns Pirro: 2 wounded National Guard ...

There are several reasons to consider using brushed DC motors as generators in particular applications, notes Sunil Kedia of Portescap in a new Machine Design article. “Brushed DC motors are less ...

Everyone knows that if you spin the shaft of a DC motor, it will generate power. [Vapsvus] has found a novel way to do this with no direct mechanical connection to the shaft. He simply taped a loop of ...

Any stepper motor can be used as a generator. In contrast to other generators, a stepper motor produces a large induced voltage even at low rotational speeds. The type used here, with a DC resistance ...
