一、噪声、振动指标的确定目前国内外电机的噪声、振动标准,均处于变革时期。在国际上,主要是采用新的考核方式和提高要求,如噪声方面,IEC 全部采用声功率级,并使指标值降低2分贝左右;振动方面,采用考核电机的振动速度,其考核指标,在2、4极部分,几乎是我国老标准的一半。在国内,电机的噪声、振动标准尚在报批之中。根据 Y 系列样机的普测结 First, the noise and vibration indicators to determine the current domestic and international motor noise, vibration standards, are in a period of change. In the international arena, the main method is to adopt a new assessment and improve the requirements, such as noise, IEC all adopt the sound power level, and the index value is reduced by about 2 decibels; Vibration, the use of assessment of the motor vibration speed, the assessment indicators in The 2,4 pole is almost half the old standard in our country. In China, the motor noise and vibration standards are still being submitted for approval. According to the Y series prototype general conclusion
