PURPOSE: A device for switching the winding of a three-phase motor is provided to easily perform a winding operation compared to multi-winding by implementing a wiring operation with single winding. CONSTITUTION: A three-phase motor(110) includes a stator, a first coil group(111), a second coil group(112), and a center tap(A_tab). A coil wound in a slot consists of a single winding. A stator includes at least 2n slots(1~12) corresponding to each phase(A,B,C). A first coil group is formed in a series connection of a coil wrapped in the first slot(A1) of each phase and a coil wrapped in a third slot(A7). |
