Abstract: Various embodiments relate to a motor in which a structure of an insulator is improved. The motor includes an upper insulator coupled to a top face of a stator core. The upper insulator includes a power terminal unit connected to each of 3-phases power lead wires; and an upper insulator body for insulating the power terminal unit from the stator core. The upper insulator includes protrusions radially protruding from the upper insulator body. Each protrusion has a guide hole defined therein for receiving each of the 3-phases power lead wires.
