研究了无槽参数电机的声学噪声产生原因和降噪能力，并与普通电机进行了比较。结果表明，由于参数电机无槽、无齿，其声学噪声比普通电机低。当电机由具有方波等高频分量的源运行时，参数电机的噪声增量比普通电机的噪声增量小。该参数电机适合在安静的环境中使用。参数电机的声学噪声主要是由碰撞产生的，电机铁心采用6.5%的硅铁片可以降低噪声。通过将转子轴压入滚珠轴承，对绕组进行清漆浸渍，并将电机的部件用框架封闭，可以进一步降低参数电机的声学噪声。>；
The causes of acoustic noise generation and the capability of acoustic noise reduction of a slotless parametric motor have been investigated, and are compared with those of an ordinary motor. It was clarified that the acoustic noise of the parametric motor is lower than that of an ordinary motor, because the parametric motor has no slot and no tooth. When the motors are operated by a source with high-frequency components such as a square wave, the increment of the acoustic noise of the parametric motor is smaller than that of an ordinary motor. The parametric motor is suited for use in a quiet environment. The acoustic noise of the parametric motor is mainly generated by the clattering, and may be reduced by using 6.5%Si-Fe plates for the cores of the motor. The acoustic noise of the parametric motor can be reduced more by pressing a rotor shaft into the ball bearing, performing the varnish impregnation of windings, and enclosing the components of the motor by a frame. >
