THE STUDY OF MECHANICAL POWER MEASURING METHOD AND INSTRUMENT FOR ASYNCHRONOUS MOTOR WITH ELECTRONIC COMPENSATOR

本文在原理与方法上,论述了一种新型的异步电机机械功率与电功率测试仪器。作者提出利用加反向安匝与分流电路以减弱仪表线圈磁场的补偿原理。文章介绍三个特殊的电子补偿器及本仪器的实验结果。

This paper discusses, in principle and method, a new mechanical power and electrical power instrument for asynchronous motor. The author presents the compen-sation principle by means of decreasing coil magnetic field of the meter with anti-direction ampere turns and divided current circuit. The paper introduces three special electronic compensators and the instrument experiment result.
