成果简介	NOVELTY - The motor has a stator, a rotor (1) and a cooling system with Peltier elements (2). The rotor is external, and the stator comprises a stator package (3) with openings in the teeth (4) and yoke (5). A radiator frame (6) is fixed in the inner cylindrical surface of the stator package and a plate (7) with openings. The cooling system is designed in such a way that heat pipes (8) are installed in the openings in the teeth and yoke of the stator package and the plate, and contacts the Peltier elements fixed on the radiator frame. The space between the heat pipes and the openings in the teeth and yoke of the stator package and the plate is filled with heat-conducting material. The stator package is heated by the currents flowing through the windings of the stator during the operation of the electric motor. The heat is transferred to the frame-radiator and dissipated into the surrounding space from the hot side of the Peltier element. USE - Highly efficient contactless electric motor for unmanned aerial vehicle. ADVANTAGE - The efficiency of electric motor cooling is increased by intensive heat removal from the electric motor stator package to frame-radiator using heat pipes and a Peltier element. The claimed utility model allows improving the cooling of an electric motor for unmanned aerial vehicles. The electric motor improves heat dissipation and reduces losses in the stator package, and achieves an increase in the flight range of the unmanned aerial vehicle, due to lower current consumption by the power plant of the unmanned aerial vehicle. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a longitudinal section of a three dimensional (3D) model of a highly efficient contactless electric motor. 1Rotor 2Peltier element 3Stator package 4Tooth 5Yoke 6Radiator frame 7Plate 8Heat pipe
