摘要 磁致伸缩和叠压影响是引起非晶合金变压器振动噪声的主要原因,而在硅钢片电机的振动噪声计算中这两种因素经常被忽略。为此本文对非晶合金电机振动噪声影响因素进行了深入研究。首先,基于压磁方程建立了磁—机械耦合数学模型。以一台2.1kW非晶合金永磁电机为例,考虑磁致伸缩和叠压影响,应用二维有限元计算了该电机在不同供电条件下的磁场分布、形变和振动加速度。在此基础上分析了定子铁心周围声场分布,通过实验验证了计算方法的有效性。之后,通过电磁力、磁致伸缩和叠压三种影响因素对硅钢片电机和非晶合金电机振动噪声影响的研究发现:磁致伸缩对硅钢片电机的振动噪声影响较小;磁致伸缩和叠压影响对非晶合金电机振动噪声影响较大,在计算非晶合金电机振动噪声时磁致伸缩和叠压影响不能被忽略。

Abstract:Magnetostriction and overlying effect,which are neglected in calculation process of vibration and noise for silicon sheet motor, are the main course of vibration and noise in amorphous metal transformer.This paper studied the factors influenced the vibration and noise of amorphous alloy motor intensively. Firstly, the magneto-mechanical coupling model is established based on piezomagnetic equation. Taking a amorphous alloy permanent magnet motor of 2.1kW as an example,the magnetic field distribution, deformation and vibration acceleration under different power conditions are calculated using 2D FEM in consideration of magnetostriction and overlying effect. On this basis, the sound field distribution around stator core is analyzed, its validity of calculation method is tested by the experiments. Then, through the study of three influence factors, electromagnetic force, magnetostriction and overlying effect,on the vibration and noise of silicon steel sheet motor and amorphous alloy motor,conclusions are: the magnetostriction has little effect on the vibration and noise of silicon steel sheet motor ,but it is on the contrary for amorphous alloy motor. Magnetostriction and overlying effect can not be ignored on calculating the vibration and noise of amorphous alloy motor.
