目前已经用电子计算机系统地研究电动机的电磁噪声问题。随着电动机功率的增加,在中大型高速电动机中.气动噪声大于电磁噪声,对于一般工业用电动机,必须考虑电磁噪声和气动噪声,采取措施予以降低。电磁噪声受定、转子槽配合、绕组设计、导磁率和类似参数的影响。在发展电动机系列时,采用电子计算机最佳选取上述参数。有时为了统筹考虑其他电气数据,设计的电动机并不总是噪声特
At present, electronic systems have been used to systematically study the electromagnetic noise of electric motors. With the increase of motor power, in medium and large high-speed motors, aerodynamic noise is greater than electromagnetic noise. For general industrial motors, electromagnetic noise and aerodynamic noise must be taken into account and measures should be taken to reduce it. Electromagnetic noise is subject to determination, rotor slot coordination, winding design, magnetic permeability and similar parameters. In the development of the motor series, using the best selection of electronic computer parameters. Sometimes in order to consider other electrical data, the design of the motor is not always noise
