能耗制动在小型绞车上的应用

Application of Dynamic Braking to Small Winch .

指出了小型绞车在正常减速停车时采用机械工作闸制动的缺点,阐明了能耗制动装置在绞车上使用所带来的制动平稳、节省零配件、工作环境条件好等优点,解决了在设计其电控回路及保护回路时应注意的几个关键技术问题。

The paper points out the disadvantages of which small winch is applied machinerybrake to stop, expounds the advantages-braking stability,saving parts andcomponents,good working environment,which is caused by the application of dynamic braking device to winch, and solves several key technical problems which should be noted in the design of control and protect circuit.
