本文分析了磁力悬掛的意义,说明了以可动部分磁力悬掛电度表代替有轴承的电度表的优点,同时也可在其他仪表和机构中采用。本文还介绍了磁力悬掛的种类和结构形式,以及半稳定磁力悬掛的理论和计算与稳定磁力悬掛垂直推应力的计算髡咧赋龃永砺凵辖菜淙晃榷ù帕π鼟熳詈?但因半稳定磁力悬掛的结构加工较方便,故推荐在实际中应用。作者建议制造悬掛磁铁时使用适当的磁性粉末压制,因这种方法价廉、加工准确并可大量生产。
This article analyzes the significance of magnetic suspension, illustrates the advantages of using a movable part of the magnetic suspension meter instead of bearing the meter, but also can be used in other instruments and institutions. This article also introduces the types and structure of magnetic suspension, as well as the theory and calculation of semi-stable magnetic suspension and the calculation of the vertical thrust of stable magnetic suspension. 髡 咧 Fu 龃 Yong 凵 凵 jurisdiction of food 淙 Huang 榷 ù ù Pi 鼟 π熳 詈? But because of semi-stable magnetic suspension structure is more convenient, it is recommended in practice. The authors recommend using appropriate magnetic powder for the manufacture of suspended magnets, because this method is inexpensive, accurate and can be mass produced.
