摘要
作为三相感应电动机单相运行的一种特殊接法 ,SEMIHEX连接可使三相感应电动机在单相电源上接近对称运行。利用对称分量法对其三相对称运行条件进行了分析 ,给出了三相对称运行时的相量图 ,并对该联接方式下电动机的运行特性进行了试验研究。
As one of the connections for three phase induction motor to operate from single phase supply,SEMIHEX connection can enable three phase induction motor have approximated symmetrical operation.Inthis papper,the method of symmetrical component is used to obtain the condition for symmetrical operation,and the phasor diagram of symmetrical operation is given.Experimental researches are carried out for operation characteristics of SEMIHEX connected three phase induction motor,and it is proved that SEMIHEX connection has higher efficiency and power factor in comparison with three phase connection.
