Abstract
The utility model relates to a new structure high performance DC gear motor, comprising a rotating shaft and a skeleton, the rotating shaft is provided with a rotor iron core, the skeleton is inserted into the rotor iron core, the outer peripheral surface of the wound rotor iron core is provided with a closed ring, the inner diameter surface of the closed ring is fixed with the rotor iron core in a press-in cooperation manner, and the rotor iron core is fixed on the skeleton. The closed ring is of an annular structure, and sealing glue layers are arranged on the two side faces of the framework and the wound armature. The structure of a brush motor rotor scheme is modified, and a traditional rotor is subjected to closed slot design, so that the purposes of reducing the tooth slot torque, improving the operation stability of a solar mechanism and reducing stray loss are achieved, and the motor efficiency is improved. And after being sealed, the main body part of the rotor iron core is encapsulated by glue with high heat conductivity coefficient in a large area, so that the heat dissipation performance of the whole winding is improved, the temperature rise and copper loss are reduced, and the motor efficiency is improved.
