螺杆泵井节能电动机应用效果分析

Applied effect analysis of energy-saving motor in screw pump well

稀土永磁电动机是使用钕铁硼稀土永磁材料,采用异步起动、同步工作方式,由于转子转速与定子旋转磁场完全同步,无转差损耗,不仅能在额定负载时有较高的效率和功率因数,而且在轻载时也能有较高的效率和功率因数。文中对其工作原理,选井原则,应用效果分析等方面进行了论述。

The rare earth permanent magnetic motor is made from Ndfeb.The working model of line-start and synchronized working has been adopted.Because the rotate speed of rotor is synchronized with a rotating magnetic field,there is no wastage under different rotating and there is higher efficiency and power rate under whether rated load or light load.The working principle,well selection principle and application effects have been discussed in this paper.
