摘要
简要介绍了转筒式电涡流缓速器的基本机械结构,建立了转筒式电涡流缓速器制动力矩计算模型。基于电涡流理论和电磁感应定律,推导了气隙磁感应强度、制动功率、制动力矩计算公式,为转筒式电涡流缓速器的优化设计及温度场分析等提供了理论基础。以1200N·m转筒式电涡流缓速器为例,比较了制动力矩的理论计算值和试验值,可以看出它们基本吻合。
The mechanical structure of a rotary drum eddy current brake is introduced briefly and the caculation model of the braking torque was established in this paper.The calculation formulae for its braking torque,air-gap magnetic induction and braking power is deduced based on the eddy current theory and the electromagnetic induction law.After verification by experiment,the braking torque calculated theoretically is in good agreement with the experimental result for 1200 N·m rotary drum eddy current brake.
