【 摘 要 】

This paper considers the possibility of applying a drawworks DC motor and a magnetic powder brake as an active bit feed rate regulator. A dynamic mathemat-ical model of the DC motor is presented. The drawworks electric drive control system is described. A computer simulation model of the DC motor, its control system, the mag-netic power brake, and the drill string has been developed with Simulink environment. The drill string is modeled as a spring element with stiffness and compression force being equal to the stiffness and dead weight of an actual drill string. The results from the simulation of a drawworks electric drive operating in a drill string lift mode and in a bit feed mode are presented.
