[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 ...

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 ...

The Genecon motor/generator is a motor or hand cranked DC generator that is used to drive another Genecon motor/generator and/or to light a series of LEDs. The Genecon motor/generators are fragile.

A DC motor/generator is connected to a light bulb. When a mass spins the generator, the light bulb emits light. If you have any questions about the demos or notes you would like to add to this page, ...

DC machines can be classified as self-excited, separately excited, permanent magnet (PM), and brushless. Self-excited machines can be further classified as shunt, series, and compound. Compound ...
