Recent studies indicate the level of knowledge and implementation of motor system energy-efficiency measures is low. A plethora of information on motor system design, best practices, purchasing, and ...

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 ...

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 ...

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 ...
