Christine and Scott Gable are hybrid auto and alternative fuel experts who have brewed their own biodiesel and traveled 125,000 miles on waste vegetable oil. Electric vehicles rely exclusively on ...

Most motors and generators use stator cores made of silicon iron, which places upper limits on their operating frequencies. Engineers at Light Engineering Inc. build their motors and generators with ...

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 ...
