摘要
采用AT89S52单片机为核心,外扩采样、显示、保护、通信等电路构与一个高性能转矩转速测试仪,用于测量电机的输出转矩、功率和转速。分析了转矩和转速测量原理,测试仪的转矩测量采用了能量转化法,转速测量采用测速范围较宽的M/T测速法。介绍了其硬件结构和软件设计。经过实验验证,所设计的测试仪不但提高了测量精度,而且简化了硬件结构,降低了成本;测试结果与实际相符。
A new kind of torque and rotational speed measuring instrument was constructed with the AT89S52 single chip microcomputer,sampling circuit,displaying circuit,protection circuit and communicating circuit,which can measure the motors output torque,power and rotational speed.The measurement principle of torque and rotational speed was analyzed.The new method presented to measure torque was the transformation of energy,and the method of measuring rotational speed was M/T,which can measure wider speed.The hardw...
