【摘要】：以45 k W双盘异步式永磁涡流传动调速器为研究对象,建立了永磁涡流传动调速器机械能与磁能之间的能量平衡方程。结合虚拟仪器技术,设计并搭建了磁力耦合调速器性能测试综合试验平台,着重对永磁涡流传动调速器的调速特性、机械特性和温度特性进行了试验测试与研究分析。结果表明,永磁涡流传动调速器在拖动电机转速一定条件下,恒负载情况时,负载输出转速与气隙距离之间近似呈二次函数关系;且在不同的负载条件下,永磁涡流传动调速器有不同气隙距离下的调速特性;气隙距离恒定时,负载大小与负载输出转速近似呈线性关系,机械特性偏"软";永磁涡流传动的拖动电机输出转速、负载和气隙距离恒运行情况下,永磁盘、散热片及中部连接轴承温度最终处在很小的范围内波动,呈现稳定状态。试验与分析结果可对进一步研究磁力耦合调速器的工况使用及优化设计提供指导与参考依据。
[Abstract]:An energy balance equation between mechanical energy and magnetic energy of a 45 K W dual-disk asynchronous permanent magnet eddy current speed governor is established. Combined with virtual instrument technology, a comprehensive test platform for the performance test of a magnetic-force coupling speed governor is designed and built, focusing on the speed control characteristics of the permanent magnet eddy current speed governor. The results show that the relationship between the output speed of the load and the air gap distance is quadratic function under the condition of constant load, and the permanent magnet eddy current drive has different air gap under different load conditions. When the air gap distance is constant, the load size and the load output speed are approximately linear, and the mechanical characteristics are "soft"; when the permanent magnet eddy current drive motor output speed, load and air gap distance are constant, the temperature of the permanent magnet disc, the radiator and the central connecting bearing will fluctuate in a very small range at last, showing a very small fluctuation. The test and analysis results can provide guidance and reference for further study of the working condition and optimization design of magnetic coupling governor.
