FBG Based Air-gap Magnetic Flux Density Dynamic Measurement and Analysis
摘要
Abstract
A FBG based magnetic bearing air-gap magnetic flux density measurement test system was constructed,air-gap magnetic flux density was measured through a FBG sensing component under 3 rotating speeds（1080r/min, 1320r/min and 1500r/min） and 6 coil-currents（0. 5A, 1A, 1.5A, 2.0A,2.5A and 2.95A）,the measurement results were analyzed with FFT method. It is concluded that there is virtually consistency between the measurement results and finite element calculations and it is feasible to utilize the FBG sensing component for dynamic measurement of air-gap magnetic flux density.关键词
