| Abstract: | The characteristics of the rig drawworks driven by variable frequency motors are introduced. Based on an analysis of operational performance of variable-frequency regulating and regenerative electric power braking of the drawworks, the operating principle and process of regenerative electric power braking is described. And the advantages of applying the regenerative electric power braking on hoisting drum brake are indicated as follows: (1) realizing conveniently four-quadrant operation of the motor; (2) ensuring the drawworks running without bump; (3) achieving easily automatic feed and digital control and braking in emergency case. |
