Experimental Research on Performance of Permanentmagnetsynchronouselectricwheel Loader

摘要:

对永磁同步电动轮驱动技术在装载机上的性能表现进行了理论与试验分析,表明基于弱磁控制算法的永磁同步电动轮能完全适应装载机的行驶、制动、牵引和转向等各种工况，也能相互高效协同工作.用改造的ZLM15B装载机在水平水泥路面上进行了上述工况试验.试验数据表明,永磁同步电动轮在行驶和牵引工作时效率可达90%以上，能自适应差速转向，制动过程中电动轮之间转速、转矩的一致性非常好.

Abstract:

Performance of a wheel loader with permanentmagnetsynchronouselectricwheel driven technologies was studied by theoretical and experimental methods.Theoretical analysis shows that electric wheels of the loader,based on fieldweakening control algorithm,can be well adapted to the traveling,braking,traction and steering conditions with cooperative and efficient work.Experiments on an improved ZLM15B wheel loader under the above driving conditions were carried out on the level cement road.Experiment results further validate that the traveling and traction efficiencies between permanentmagnetsynchronouselectric wheels are both better than 90%,which can well adapt differential steering with good consistency of the speed and the torque between electric wheels under braking.
