至今,还没有一种简单而实用的方法,能够用来精确地测量正、反向转矩。这里介绍的测量方法却适于对转矩和转速同时进行测量,亦即对功率进行测量。在大量的转矩测量方法中,实用的装置是比较灵敏的,因为转矩传感器或转换器随轴转动。但从转换器输出的信号必须送到固定的仪器中进行处理。这通常是用电刷与滑环装置来实现,而这种装置存在许多困难。 So far, there is no simple and practical method that can be used to accurately measure positive and negative torque. The measuring method described here is suitable for simultaneous measurement of torque and speed, ie measurement of power. In a large number of torque measurement methods, the practical device is relatively sensitive, because the torque sensor or converter with the shaft rotation. However, the signal output from the converter must be sent to a fixed instrument for processing. This is usually done with brushes and slip rings, which have many difficulties.
