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 ...

To fully appreciate the chief advantages of linear motors, it is helpful to compare them to ballscrews, another high-precision rotary-to-linear transmission system. Although typical ballscrews are ...

China's first linear-motor-powered metro train recently left the station. The first high efficiency linear motor (LM) propulsion system to power a metro train was successfully tested and validated at ...

Pneumatic and hydraulic linear actuators operate on pressure differentials; electromechanical actuators are either linear motors or rotary types. Other differences abound. Mark Lemire, Product manager ...
