Features: 1. High-accuracy, one-time forming rotor made of high-quality materials, high conductivity, wear-resistant and long service life 2. It adopts pure copper group, small electric group, low calorific value and low loss 3. The carbon brush has good commutation performance, long service life, good electrical and thermal conductivity and good lubrication performance. 4. The degree of wear of the carbon brush directly determines how long the motor can be used. 5. High-strength magnetic tile, long service life, strong power and greater torsion 6. Adopt a fully enclosed structure to prevent dust from entering the inside of the motor. 7. Simple structure, convenient maintenance and small size, which can effectively reduce weight, save space and be reliable. 8. The gearboxes are all made of high-quality metal gears. They have good impact resistance and durability, reducing noise and delaying the service life of the gearbox. 9. Generally used in smart cars, robots and printers Specification: Condition: 100% Brand new ReductionRatio No-Load Rated Locked-Rotor L Size Rated Voltage Speed Current Speed Current Torsion Torsion Current V 10%RPM A 10%RPM A KG.CM KG.CM A MM 4.4 6 1360 0.04 1000 0.16 0.1 0.4 0.6 18 9.6 6 620 0.04 500 0.16 0.2 0.9 0.6 17.5 21.3 6 280 0.04 200 0.16 0.4 2 0.6 19 35.5 6 170 0.04 130 0.16 0.69 3.3 0.6 21 46.8 6 130 0.04 100 0.16 0.9 4.4 0.6 21 78 6 77 0.04 60 0.16 1.5 5.5 0.6 23 103 6 60 0.04 50 0.16 2 7.3 0.6 23 130 6 46 0.04 40 0.16 2.5 9.2 0.6 25 171 6 35 0.04 30 0.16 3.3 Do not block or instantaneous load reversal 25 226 6 26 0.04 20 0.16 4.4 25 377 6 16 0.04 15 0.16 7.3 27 500 6 12 0.04 10 0.16 9.7 27 Optional Style: 1000RPM, 500RPM, 200RPM, 130RPM, 100RPM, 60RPM, 50RPM, 40RPM, 30RPM, 20RPM, 15RPM, 10RPM Package List: 1 x Motor 1 x Motor Base 1 x Tire 1 x Coupling 1 x Hex Socket Wrench 2 x Coupling Supporting Screw 6 x Cross Big Screw 1 x Cross Small Screw .
