摘要 为研究变频电机在不同温度、不同谐波下的电磁性能及考虑硅钢片磁致伸缩影响的振动特性,该文首先对变频电机铁心硅钢片在不同温度及谐波下的磁性能展开研究,给出硅钢片在不同温度及谐波下的B-H曲线、B-P曲线及磁导率曲线。其次对硅钢片的磁致伸缩特性展开了测试与分析,给出硅钢片的蝴蝶曲线及磁致伸缩单值曲线。基于硅钢片磁特性及磁致伸缩特性的测试结果,对1 140V/75kW变频电机的电磁性能及振动展开仿真分析,在仿真过程中考虑了温度、谐波及磁致伸缩对变频电机铁心硅钢片性能的影响。最后对1 140V/75kW变频电机展开振动实验,为变频电机的电磁-振动分析提供了一个新的思路。

Abstract:In order to study the electromagnetic properties of the variable frequency motor at different temperatures and harmonics as well as the vibration characteristics considering the magnetostriction effect of silicon steel sheet,the magnetic properties of the silicon steel sheet in the core of the variable frequency motor at different temperatures and harmonics are first studied.The B-H curve,B-P curve and permeability curve of the silicon steel sheet are given.Secondly,the magnetostrictive characteristics of the silicon steel sheet are tested and analyzed to obtain the butterfly curve and the magnetostrictive single value curve.Based on the above test results,the electromagnetic performance and vibration of 1 140V/75kW variable frequency motor are simulated.The influence of temperature,harmonics and magnetostriction on the performance of silicon steel sheet isconsidered in the simulation process.Finally,avibration experiment of 1140V/75kW variable frequency motor is carried out,which provides a new idea for electromagnetic-vibration analysis of the variable frequency motor.
