<p>PURPOSE: An electric motor using an etching thin film coil winding is provided to improve the output by removing a rotor core and making a small inertia moment. CONSTITUTION: A bracket(322) is coupled to the outside of a rotary shaft(321). A permanent magnet(323) is inserted and installed on the outside of the bracket. An etching thin film coil winding(324) is inserted and installed to the outside of the permanent magnet. An End cap(360) is coupled to the outside of the circular printed circuit board(350). A bearing(370) is coupled to rotate the rotary shaft from the outside of the End cap.
