摘要

本文研究了三相一速和双速笼形转子全封闭外冷异步电动机的磁噪声。调查包括Dahlander绕组连接或单独绕组的两速三相感应电动机，额定转速为3000/1500 rpm, 1500/750 rpm, 1500/1000 rpm。所研究的电机(由SC Electroprecizia SA制造)被放置在半消声室中，以确定噪声与频率特性(频谱图)。本文是基于对这些谱图的分析得出的结果和结论。文中还指出了定子层片堆积时施加的压力对磁噪声水平的重要性。

The magnetic noise of three-phase induction motors with squirrel cage rotors

In this paper a study of the magnetic noise in three-phase one and two-speed cage rotor, totally enclosed, externally cooled induction motors is presented. Investigations include two-speed three-phase induction motors with Dahlander winding connection or separate windings, with rated speeds of 3000/1500 rpm, 1500/750 rpm, 1500/1000 rpm. The investigated motors (manufactured by SC Electroprecizia SA) were placed in a semi-anechoic chamber in order to determine the noise versus frequency characteristics (spectrograms). The paper is based on results and conclusions obtained after analyzing these spectrograms. The importance of the pressure applied by the stacking of the stator laminations for the level of the magnetic noise is also presented.
