Abstract
According to an embodiment of the present invention, a three phase motor in which a structure for preventing an electrical short circuit is applied includes a stator including a base portion having a hollow formed therein and a plurality of winding portions extending from the base portion toward the hollow and formed apart a predetermined distance from each other; a rotor having a plurality of magnets inserted therein and disposed in the hollow apart from ends of the winding portions; and an insulation sheet disposed between the winding portions abutting each other to prevent an electrical short circuit among the coils wound around the winding portions abutting each other.
