本文指出,采用双斜槽结构转子,降低电机的电磁噪声甚为有效;并推荐气隙磁密B_δ的值。文中介绍了具有低的轴承噪声的铁铜基石墨粉末冶金含油自润滑滑动轴承;并推荐了游隙尺寸。
This paper points out that it is very effective to reduce the electromagnetic noise of the motor by double-skew rotor. The value of air gap flux density B_δ is recommended. In this paper, an iron-copper-based graphite powder metallurgy oil-bearing self-lubricating sliding bearing with low bearing noise is introduced; and the clearance size is recommended.
