Feature:1. Precise style can achieve maximum energy conversion. The rotor is precisely balanced, smoothness improves reliability and maximum speeds.2. High purity copper winding maximizes efficiency, high-strength magnets provide stable brush motor performance.3. Excellent torques and long life, direct welding wiring guide, providing flexible welding options.4. 540 brush motor, high torques is used for drifting of climbing car and large foot car, strong magnetic force of bidirectional bearing, small heat generation and large power.5. The carbon brush can also be changed, because the external carbon brush can work for a long time.Specification:Condition: 100% Brand NewItem Type: RC AccessoriesMaterial: Metal and PlasticColor: BlackMotor:Speed: 35T, 45T, 55T (optional)Length: Approx. 53mm / 2.1inDiameter: Approx. 36mm / 1.4inShaft Length: Approx. 12mm / 0.5inShaft Diameter: Approx. 3.17mm / 0.1inOperating Voltage: 7.2-7.4VMaximum Voltage: 12VESC:Direct Current: 60AExplosion Current: 320APower Supply: 2~3S Lithium Battery, Nickel Hydrogen Battery 5~9SBEC: 5V/2AProduct Size: Approx. 43 x 29 x 27 mm / 1.7 x 1.1 x 1.1 in (without Cable)No-Load Current: 1.4AContinuous Output Current: 320a (forward), 160a (rear), 270a (braking)7.2V Voltage No-Load Speed:35T: 12000rpm45T: 10000rpm55T: 8000rpm.Package List:1 x Brush Motor1 x 320 Brush ESCNote:1.
