1 Pcs DC11V 12V 18V 21V Brushless Motor Electric Blade Fan Motor 125W/135W High Power Strong Suction Metal Impeller for Vacuum Cleaner(D DC 12-21V 120W)

MotorsSpecification:Note: The DC brushless motor is equipped with a drive board. It is strictly forbidden to connect the positive and negative poles of the power supply. The red line is connected to the positive pole and the black line is connected to the negative pole. If the connection is wrong, the drive board will burn out.Motor connection:1. Red wire (thick): positive power supply pole2. black line (thick): power negative pole3. red line (thin): motor on/off; switching high and low gears4. black line (thin): GNDAfter connecting the power supply, the red line (thin) and the black line (thin) contact about 2.5 seconds to start, this time is a low-speed gear; short for a while, switch to high-speed gear; and then short for a while, the motor shutdown.Model A data:Voltage: DC12V; Current: 4.5A (First gear, low gear.) ; Power: about 55 W; Speed: 80000rpmVoltage: DC12V; Current: 10.5A (Second gear, high gear.); Power: about 125 W; Speed: 110000rpmNegative pressure: low-speed gear 10Kpa, high-speed gear 17 Kpa (error ± 5%)Model B data:Voltage: DC18V; Current: 4.6A (First gear, low gear.) ; Power: about 82 WVoltage: DC18V; Current: 7.9A (Second gear, high gear.); Power: about 142 WNegative pressure: high-speed gear 17 Kpa (error ± 5%)Model C data:1. Rated voltage: DC 12.6V2. suitable voltage: DC 10V - 15.9V (Below 10V or higher than 16V, the motor does not work.)3. no-load Power: about 100WModel D data:1. Rated voltage: 21VDC (5C 2000mA 6 series power battery)2. Rated current: 21V, high-speed gear no load 5.8A; plugging current 6.7A (±5%)3. Voltage range: DC 12 - 22V4. Motor type: 3-phase DC brushless (instantaneous starting current 30A)5. Direction of rotation: CCW, motor rotation direction from the air inlet visually counterclockwise6. Rated input power: 70W for low-speed gear, 140W for high-speed blocking power (accuracy ±5%)7.
