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 ...

The AC induction motor is often referred to as the workhorse of the industry because it offers users simple, rugged construction, easy maintenance, and cost-effective pricing. These factors have ...

Engineers whose designs include medium-sized motors have a great opportunity to save energy and improve the performance of their products. Recent advances in motor-control systems make implementing ...

Electric dc brush motors have traditionally used wire-wound armatures that move through a magnetic-flux air gap. Engineers at ThinGap Motor Technologies, Santa Barbara (www.thingap.com), have come up ...

Legacy designs of variable frequency drives (VFDs) used optocouplers or pulse transformers for isolation and mated them together with gate driver ICs. A more integrated approach, though, uses ...
