Abstract :
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. In this paper, the method of symmetrical component is used to obtain the condition for symmetrical operation, and the phasor diagram for symmetrical operation is given. Experimental studies for operation characteristics of SEMIHEX-connectecl three-phase induction motor are performed on prototype motor. It is proved that SEMIHEX connection has higher efficiency and high power factor in comparison with three-phase connection.
