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 ...

When someone says, “I’m here from the government and I’m here to help you,” skepticism is probably one of your reactions. With the passage of the Energy Act of 1992, however, the government may really ...

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 ...

At COP28 in Dubai last year, the global community pledged to work together in order to collectively double the global average annual rate of energy efficiency improvements from around 2 percent to ...
