換電動機。[Claims for Utility Model Registration] (1) In a pole conversion motor that changes the number of poles of a stator by changing the connection state of the single stator winding to the power supply side, A first and second fixed terminal group consisting of a plurality of fixed terminals are provided between the power source and a dummy terminal is provided in one of the first and second fixed terminal groups, respectively. Fixed terminal groups are arranged symmetrically with respect to each other, and the dummy terminals are used as interlock signal generation means for mutually interlocking the first and second fixed terminal groups. Conversion electric motor. (2) When the power cable is connected to the fixed terminal group on the side where the dummy terminal is provided, the dummy terminal generates the interlock signal in cooperation with a detection means that detects the connection. A pole change electric motor according to claim 1 of the utility model registration claim, characterized in that:
