GEARMOTOR Russian patent published in 2014 - IPC H02K9/28 H02K9/22 H02K5/14 H02K7/116 H02K11/00 

FIELD: electricity.

SUBSTANCE: in the gearmotor, the mounting assembly (26d) of the brush holders of the housing of the reducing gear (26) there are series-arranged two flat surfaces (19b) ad two arched surfaces (26b) such that they form an ellipse. One of the two flat surfaces is formed with first heat-removing elements (26i), and two brushes (20) and (20) of the motor are mounted near the first heat-removing elements (26i) on a block (19) of brush (20) holders, built into the mounting assembly (19) of the brushes, situated in the mounting assembly (26d) of brush (20) holders. According to the present invention, the first heat-removing element is formed on the external peripheral surface of the housing of the reducing gear, situated on the back surface of the mounting part, and said two brushes are situated further from the control board and near the first heat-removing element, such that heat released by the brushes is transferred to the first heat-removing element.

EFFECT: efficient dissipation of heat generated by brushes, thereby reducing the amount of heat transferred from the brushes to the control board in a gearmotor, which solves the problem operating such a motor for a long period of time.
