Investigation on All Digital Control System of Brushless DC Motor for Beam-Pumping Unit

Abstract:

In order to drive beam-pumping unit with brushless DC motor (BLDCM), a kind of motor speed regulator was investigated. When pumping unit is in up stroke, BLDCM is power-driven; when in down stoke, pumping unit is braked by BLDCM. To meet the operation mode, PI double closed loops control strategy and Pulse Width Modulation (PWM) are applied. Simulation and test in field show that our design has good control effect and popularizing value.
