Discover how to convert a small AC electric motor into an efficient electricity generator using basic tools and materials.

[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 ...

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 ...

From tiny hysteresis motors that drive electric clocks to huge synchronous motors that develop more than 50,000 hp, the alternating current (AC) motor has become an indispensable part of everyday life ...

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 ...

DC Motors were king in industry up until the late 1980s; These motors were popular because they were able to run to a variable speed setpoint, and they could run at full torque from stall to base ...
