[ALL-METAL GEARS]: High-temperature resistance, high abrasion resistance, strong load capacity, sturdy and durable, effectively protect the motor body. [PURE COPPER WIRE CORE ROTOR]: With precision winding technology, the geared motor power instant increased by 30%. [D SHAPED OUTPUT SHAFT]: Using high hardness steel, good toughness, impact resistance, the quality of the bearing and the service life of the gear motor are improved, extremely durable. [POSITIVE-NEGATIVE ROTATION]: You also can adjust the speed, but the motor speed can only be reduced, can not be raised. Low noise and high torque, such as 10rpm can drive 15 kilograms.
