摘要
电磁噪声是电机噪声的一个重要组成部分。电磁噪声的激励源是电磁交变力引起的电机结构,特别是非旋转机构的振动。本文使用电磁仿真软件和声学仿真软件,实现了从电磁力预测到振动噪声预测的过程。
Electro-magnetic noise plays a very important role in an electro motor noise radiation. Electro-magnetic noise is mainly caused by vibration of non-rotational part of an electro motor, which is excited by space-variable and time-variable electronic-magnetic forces during running time. A co-simulation method by JMAG and Virtual.Lab is used to predict electro-magnetic noise of an electro motor.
