Since AC induction motors have been established as the preferred choice for industrial motors and the need for reduced power in all aspects of design is ever present, the efficiency of these motors is ...

Many engineers look at NEMA Premium grade as the gold standard for induction motor efficiency. But technical innovations now make possible even more power-miserly designs. By now, most engineers who ...

Continuing headlines about superefficient electric drives might lead some observers to wonder about the future of three-phase induction motors. The truth is that induction motors aren’t going away any ...

New and increasingly stringent efficiency standards have made motor efficiency a priority among motor manufacturers and designers of motor-driven systems. While the Energy Independence and Security ...

Adjustable-frequency drives have been billed as an energy efficient way to drive three-phase ac induction motors. Nevertheless, designers should understand that motors fed by inverter power experience ...

Energy efficiency is one of the most misunderstood aspects of fractional horsepower motors and gearmotors. It normally does not receive much attention; however, efficiency can be critically important ...

Imagine installing nearly every available form of forced induction available for the four-valve 4.6 on the motor in a boost-bashing, charge-cooling, head-to-head test. Running all four of the ...
