针对用压磁传感器或应变片力式传感器称重的传统方法存在着对传感器要求高 ,且传感器的制作和安装难度大 ,寿命短等缺陷 ,提出了利用绕线异步电动机的电磁转矩和转差率以及匀速提升时提升荷载和电动机电磁转矩之间的关系来计量提升荷载的方法。计算机仿真试验结果表明该方法可行 The traditional method of using pressure sensor or strain gauge force sensor to weigh has the defects of high requirement of sensor, difficulty of manufacture and installation of sensor, short life span and so on. The paper proposes the use of electromagnetic torque and torque of winding asynchronous motor The rate of failure and uniform lifting to enhance the relationship between the load and the electromagnetic torque to measure lifting load method. Computer simulation results show that this method is feasible
