摘要
电感不仅是电动机的一个重要参数,而且对控制系统中的电流环有重要影响。针对目前电感测试方法的缺点,提出一种动态测试方法。该方法是以电路的自激振荡理论为原理,通过设计一个LC振荡电路将电感的测量转换为频率的测量;最后,经电路处理将电感量的变化动态地反映在电压的变化上,从而实现动态测量。
Armature inductance not only is a key parameter of a motor, but also has a very important role in current control loop. Considering the shortcomings of the current inductance test methods, proposes a dynamic measurement, which bases on the theory of the circuit self-oscillation. A LC oscillating circuit is designed to gain the frequency which has relationship with inductance, and then another circuit is used to reflect the inductance change dynamically on the voltage.
