[0002] In situations where space is limited and a motor is required to drive parts, an energy-saving and waterproof micro motor is required. The energy-saving and waterproof micro motor is small in size and is convenient for installation inside situations where space is limited. At the same time, the micro motor can save energy and reduce energy consumption, and is waterproof to avoid damage to the motor when it comes into contact with water, thereby ensuring the service life of the micro motor. When the micro motor is installed, it is fixed to the installation area by a bracket.

[0003] According to CN201810349364.9, the present invention discloses a DC motor, which includes a front cover, an armature, a stator, a brush holder assembly and a rear cover assembly, wherein the rear cover assembly includes a rear cover body and a resistor assembly, wherein the resistor assembly includes a resistor cover, a resistor sheet and two inserts, wherein the two inserts are connected to both ends of the resistor sheet, wherein the resistor assembly also includes an annular bracket and two annular insulating pads, wherein the bracket is connected to the outside of the rear cover body, wherein the resistor cover is annular and its edge is connected to the edge of the bracket to form an annular cavity, wherein the resistor sheet is an annular structure formed by connecting a plurality of Ω-shaped units, wherein the two insulating pads are arranged on both sides of the resistor sheet to form a sandwich structure, wherein the sandwich structure is arranged in the annular cavity.
