新型高效单相感应电动机的设计计算方法研究

Study of a New Type of Single Phase Induction Motor with Higher Efficiency

作为三相感应电动机单相运行的一种特殊接线方式 ,与三相感应电动机在三相对称电源上运行相比 ,SEMIHEX电动机具有高的功率因数和效率。本文研究了对称运行需要满足的条件 ,采用双旋转磁场理论对其进行分析 ,给出了性能计算的具体方法 ,计算结果和试验结果的吻合 ,证明本文给出的方法是正确有效的。

As one of the connections for three phase induction motor to operate from single phase supply,in comparison with three phase induction motor operating from three phase supply,the SEMIHEX connection has so higher efficiency and power factor that can take place of the ordinary single phase induction motor.In this paper,theoretical analysis give out the method for calculating the performances .The calculated results are close to the test results,which verifies the correctness and validity of the method.
