摘要
讲述了笼型三相异步电动机的噪声测量方法和标准限值。对电机空载和负载运行时的噪声故障进行了分析,重点阐述笼型三相异步电动机空载运行时,机械和电磁两方面的噪声故障隐患表现和修理预防措施。
The noise measurement way and limited val-ue of the standard of the 3-phase asynchronous cage-rotor motor were described. The noise failure both under no-load and full-load operation was analyzed, focused on the hidden failure appearance and preventive measure in the ifelds of mechanism and electromagnet.
