Abstract: Various embodiments relate to a motor in which a structure of an insulator is improved. The motor includes an insulator module coupled to a top face of a stator core. The insulator module includes: each power terminal unit connected to each of 3-phases power lead wires; a neutral terminal unit connected to a neutral point of a coil; and an insulator body for achieving insulations between the power and neutral terminal units and the stator core, and between the power and neutral terminal units, wherein the power terminal unit and the neutral terminal unit are positioned at different vertical levels.

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.
