Permanent Magnet Motors Find its Way to Circulator Pumpstors. The development in power electronics and permanent magnet materials has now made the PMSM an attractive alternative for circulator pumps. The combination of high efficiency of this motor and ability through electronic control to adjust the pump to the actual heating requirements of the custome搜寻 发表于 2025-3-25 18:17:04

,Calculation of Surface Stress and Herring’s Formula,on of the surface stress; it has to be executed the partial derivation of Eq. (.). A more detailed analysis of this problem shows that no derivation of the Fermi function with respect to the strain.. can appear in the formula for surface stress.通情达理 发表于 2025-3-26 14:35:14
