The motor calculations presented here apply to changing conditions of a blower motor when pulley adjustments are made. However, these calculations are useful wherever electric motors are used. These ...

Motors and their associated equipment must be protected against both overload and overcurrent (short circuit or ground fault). This function is usually split, with ...

Learn important methods, formulas and calculation details to determine the power output of a coreless motor, the speed-torque curve of the motor, the current and efficiency plots, and the theoretical ...

Last spring, in response to California's recent electricity shortage, Governor Gray Davis signed a bill into law that provides financial incentives for upgrades that improve the efficiency of motor ...

Linear-motor driven plunger pumps are most efficient at transforming mechanical energy to hydraulic work in low-producing and highly deviated wells. Linear-motor driven plunger pumps (LMDPP) are most ...

Industry 4.0 is seen as the new era of manufacturing, combining technology, robotics, artificial intelligence and automation to create an efficient and effective manufacturing process. Industrial use ...

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 makes up 80 percent of the cost of owning and operating a motor over its lifespan. That’s why motor makers have spent decades trying to build ever more energy-efficient designs. But with ...

The key to equipment operating efficiently and effectively and having a positive effect on the bottom line is a connected, compact and versatile electronically commuted motor. ECMs are controlled ...

Energy efficiency always carries a price, and the federal government’s latest initiative to wring more savings from efficient electric motors offers proof. The U.S. Department of Energy (DOE) has ...
