RTTB-3型旋转力矩试验台测量技术探讨

A Probing Study of the Technolgy of Surveying Aviation Motor by Using the Revolving Torque-Test-Bench-3

RTTB-3型旋转为矩试验台是一种对电机进行自动测试并记录测试数据的设备。在实际使用该型试验台测试正常航空电机性能中，发现该型试验台在设计上没有考虑加载时冲击电流的影响，使记录的被测电机性能数据曲线有误差。探讨了RTTB-3型旋转为矩试验台在加载时对冲击电流的处理方法，以及实际使用此方法测试电动机扭矩技术。

The Revolving Torque - Test -Bench - 3 (RTTB-3) is a kind of equipment that tests.motor automatically and records the data of tests. When the author tests the property of the normal aviation motor by using RTTB-3, she discovers that the design of RTTB- 3 neglects the effect of the impact current when it is loaded, which leads to the errors in the surveyed motor proprety data graph recorded. This paper studies the method in dealing with the impact current when RTTB-3 is loaded and applies this method to the survey of the motor torque technology.
