Features: _x000D_ 1. Pure copper coil: The motor is made of high-precision rotor and high-quality materials, with high conductivity, high wear resistance and long life. At the same time, it adopts pure copper group, featured with small resistance, low heat generation, low loss, stable operation and sufficient power. _x000D_ 2. High quality carbon brush: Under the premise that other materials meet the requirements, it has good commutation performance, long service life, good electrical and thermal conductivity and good lubrication performance. The wear resistance degree of the carbon brush directly determines service life of the motor. _x000D_ 3. High strength magnetic tile: Long life, strong power, greater torque. Fully enclosed structure to prevent dust from entering the motor interior, simple structure, convenient maintenance. Small size, effective weight reduction, space saving, reliable use. _x000D_ 4. Full metal gear: The gearbox are all made of high-quality metal gears, which have good impact resistance and durability. thus extending the lifespan of the gearbox. _x000D_ 5. Wide Application: This motor is ideal for intelligent toy car, robot, printer, balance car, smart home appliance, camera rocker arm, and so on. _x000D_ _x000D_ Specification: _x000D_ Rated speed (RPM): 1000, 500, 200, 130, 100, 60, 50, 40, 30, 20, 15, 10 (Optional) _x000D_ Dimensions: _x000D_ Outer diameter: 25mm/0.98in _x000D_ Shaft length: 12mm/0.47in _x000D_ Shaft diameter: 4mm/0.16in _x000D_ Reduction Ratio _x000D_ No Load Rated Stall L Size _x000D_ Raed Voltage Speed Current Speed Current Torque Torque Current _x000D_ V 10%RPM A 10%RPM A KG.CM KG.CM A MM _x000D_ 4.4 12 1360 0.07 1000 0.3 0.1 0.4 1.8 18 _x000D_ 9.6 12 620 0.07 500 0.3 0.2 0.9 1.8 17.5 _x000D_ 21.3 12 280 0.07 200 0.3 0.4 2 1.8 19 _x000D_ 35.5 12 170 0.07 130 0.3 0.69 3.3 1.8 21 _x000D_ 46.8 12 130 0.07 100 0.3 0.9 4.4 1.8 21 _x000D_ 78 12 77 0.07 60 0.3 1.5 5.5 1.8 23 _x000D_ 103 12 60 0.07 50 0.3 2 7.3 1.8 23 _x000D_ 130 12 46 0.07 40 0.3 2.5 9.2 1.8 25 _x000D_ 171 12 35 0.07 30 0.3 3.3 Forbid stall or instantanous load reversal 25 _x000D_ 226 12 26 0.07 20 0.3 4.4 25 _x000D_ 377 12 16 0.07 15 0.3 7.3 27 _x000D_ 500 12 12 0.07 10 0.3 9.7 27 _x000D_ _x000D_ _x000D_ Package list: _x000D_ 1 x Encoder Gear Motor
