DC11V 12V 18V 21V Brushless Motor Electric Blade Fan Motor 125W/135W High Power Strong Suction Metal Impeller for Vacuum Cleaner(B DC 14.5-21V 135W)

Specification :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) : GNDModel A data :Negative pressure : low-speed gear 10Kpa,high-speed gear 17 Kpa (error ± 5%)===Model B data :Negative pressure : high-speed gear 17 Kpa (error ± 5%)======Model C data :1. Rated voltage : DC 12V2. voltage : DC 10V - 15V (higher than 16V,the motor does not work.)Test datas :voltage : DC 12.0V no-load current : 5.2A(low) / 10.0A(high)======Model D data :1.

• Powerful suction: The motor can generate strong suction, quickly sucking up common garbage such as debris and hair on the floor to keep it clean.
• Stable operation: It runs smoothly during work and can operate continuously for a long time, ensuring the smooth progress of garbage collection work and reducing interruptions.
• Flexible adaptation: It can be adapted to a variety of different cleaning scenarios. Whether it is a narrow gap or a large - area region, it can provide suction as required.
• Low - noise operation: The noise generated during operation is relatively low, which will not interfere too much with daily activities and creates a quiet cleaning environment.
