采用自适应变量泵的高效电静液作动器
|
摘要
为解决定量泵设计的电静液作动器(EHA)在大负载时热耗带来的温升问题,提出一种以自适应变量泵为基础的高效电机泵组件,利用杠杆原理,把EHA大负载时电机大扭矩输出,转换成电机小扭矩输出,从而降低电机电流造成的损耗,减小发热。通过建立物理模型,运用理论推导,分析了自适应变量泵、直流无刷电机和高效电机泵组件的特性,得出了EHA输出功率归一化曲线和电机损耗功率归一化曲线,找到了EHA在大负载下提高工作效率,解决发热的方法。
The electro-hydrostatic actuator( EHA) using fixed displacement pump cannot avoid the problem that the motor' s temperature rises fast when EHA under large load.In this article,a high-efficiency motor-pump is proposed,which uses a self-adapt variable pump.Self-adapt variable pump reduces the output torque of the motor based on the principle of lever.Then the motor' s energy loss caused by the current is lowed and motor' s heat becomes less.This article also analyzes the characteristic of self-adapt variable pump,brushless DC motor and high-efficiency motor-pump.Then the normalized plots of the EHA' s output power and motor' s loss power are gotten,which give a way to improve EHA's performance and reduce the heat under large load.
