48mm RS-887 DC Motor DC 18V 19700RPM High Speed Power Ball Bearing Engine for Electric Tools Drill Saw Lawn Mower

MotorsThis 8 - series motor features excellent workmanship and substantial materials.It feels heavy in the hand! It outperforms the 775 motor!It has a high - end configuration: with front and rear ball bearings, large - sized built - in cooling fins,a 7 - pole inner rotor, thick copper windings, and carbon brushes with high copper content, etc.With a rated voltage of 18 volts, it has a no - load speed of nearly 20,000 revolutions per minuteand a no - load power of around 80 watts. For this type of high - speed and high - power motor,the inrush current at startup is very large.Therefore, it requires a high - current power supply or a power - type lithium - ion battery for driving.Alternatively, it can be started slowly in conjunction with a DC motor PWM speed controller.This can reduce the inrush current impact on the power supply during the motor's startup.Motor Parameter:Outer diameter of motor: 48.9 MM (51.3 MM with screen magnetic ring)Motor length: 68.4 MMMotor shaft diameter: 5 MMLength of output shaft: 15.2 MMMotor weight: 464gVoltage: DC12VNo-load current: 2.5 ANo-load speed: 12700 RPMVoltage: DC18VNo-load current: 3.4 ANo-load speed: 19750 RPMPackage Include:Motor x 1pcs==========Hign-concerned Chemical : NoneModel Number : 887 MotorConstruction : Permanent MagnetProtect Feature : Explosion-proofType : Micro MotorCommutation : BrushEfficiency : IE 1Origin : Mainland Certification : NoneUse : Home Appliance
