Abstract: A motor includes a rotor assembly and a stator assembly that accommodates the rotor assembly. The stator assembly includes a stator core including tooth portions corresponding to first to third phase currents, respectively, and a coil wound around the tooth portions and defining a Y connection of the first to third phase currents, a neutral point terminal defining a neutral point of the Y connection, and power terminals configured to communicate each phase current with the Y connection. The coil includes a primary winding and a secondary winding that are wound around each of the tooth portions, that are electrically connected parallel to each other, and that are connected to each of the power terminals.
