asynchronous electric drive

Implementation of Position Control System Based on Industrial Frequency- Controlled Asynchronous Electric Drive

Positional electric drives are widely used in various branches of mechanical engineering, metal- cutting and woodworking machines, excavators, hoisting and transport mechanisms, manipulators.

Effect of sucker-rod pumping unit walking beam oscillation frequency on asynchronous electric drive

The process of oil extraction requires continuous monitoring of oil wells operation. To improve the efficiency of oil wells, it is necessary to set the optimal mode of oil pumping unit operation in which the rate of liquid pumping corresponds to that of its inflow. Many oil wells are strippers and therefore are operated intermittently.
