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 ...

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 ...

Motor control and drives are fundamental in many applications, as they allow a high degree of accuracy, which in turn translates into lower costs and greater efficiency. The vital function performed ...

One of the more popular three-phase electrical services supplied to medium-size commercial buildings is the Wye or Star configuration transformer. The name comes from the transformer’s secondary ...

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 ...

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 ...

Apple is working on a three-phase AC induction motor suitable for an Apple Car, implementing the same basic engineering and motor design principles that Tesla uses. Titled "Electric motor with bar ...
