摘要

本文的目的是对三相感应电机的杂散磁通谱进行实验分析，以说明它是如何受到轴承、齿轮箱和转子固有偏心引起的力学行为的影响。在此分析中，首先验证了机械行为对定子电流谱的影响，然后分析了感应电机外部搜索线圈中杂散磁通产生的电动势(emf)。本研究是在共用同一机械系统的两台不同的感应电机(鼠笼式和绕线转子)上进行的。

The Effect of the Mechanical Behavior on the Stray Flux in an Induction Machine Based Electromechanical System

The aim of this paper is to analyze experimentally the stray flux spectrum of a three phase induction machine in order to show how it is influenced by the mechanical behavior induced by bearings, gearbox and the inherent eccentricity of the rotor. For this analysis, the influence of the mechanical behavior on the stator current spectrum is firstly verified and then analyzed in the electromotive force (emf) induced by the stray flux in an external search coil associated to an induction machine. This study is performed on two different induction machines (squirrel-cage and wound rotor) sharing the same mechanical system.
