有限转角力矩电动机角位移特性的测量方法

The Methodology Research to Measure Angular Displacement Torque Constant of Limited-Angle Brushless Torque Motor

角位移特性是有限转角力矩电动机的主要特性之一,传统的测量方法很难准确有效的进行测量,针对当前角位移测量方法的不足,提出了基于差动螺管式电感位移传感器的高精度测量方法,最后进行了实验验证。

The characteristic of angular displacement was one of the main characteristics of the torque motor. It was very difficult to be accurate and effectual to measure with the traditional method. A design and fabricating method was presented to meet the measurement requirement of LABLTM （limited - angle brushless torque motor）, and this kind of measurement method carried on precise measurement based on differential spiral inductive transducer, finally carried on the experimental confirmation.
