Davitu DC Motor - Micro motor for cordless vacuum cleaner DC18V250W three-phase brushless fan DIY car vacuum cleaner

Mini DC brushless vacuum motor, the motor needs a signal board to startThis motor was originally used on the wireless lithium battery vacuum cleaner, the workmanship is very goodThe fan is very mini, with a diameter of only 50mm,The fan is much smaller than other vacuum cleaners in this shop.Very suitable for retrofitting car wireless vacuum cleaners.The motor has a built-in brushless drive. Although it is small in size, it is still a three-phase ultra-high-speed brushless motor.The maximum speed is about 100,000 rpm, and the bearings are imported from NMB.The motor is nominally 18V-250W,Suitable for 5S lithium battery power supply,The voltage can be used within the range of 14V~22V.Note: the positive pole of the red wire and the negative pole of the black wire,It is strictly prohibited to connect the positive and negative poles of the power supply in reverse!The motor is a high-power brushless motor,Low-speed gear no-load current is about 4A,The high-speed gear current is about 15A,The output current of the DC power supply must be greater than 18A.The battery needs a power battery.Otherwise, the air inlet of the fan must be equipped with a filter device to prevent the inhalation of foreign matter and dust from damaging the impeller and bearing.Although the motor is new,But because the goods arrive in bulk,So there may be a few bumps and scratches on the exterior,Those who pay attention to perfection should buy carefully!Voltage: 18V (14V~22V)Current: 15A (high-speed gear). 3.5A (low-speed gear)Maximum power: 250 wattsVacuum degree: 18KpaFlow rate: 0.9m³/minNoise: 85dBNet weight: 178 gramsThe fan can be used to DIY wireless vacuum cleaners, car vacuum cleaners, etc... It can also be converted into a high-pressure hair dryer by modifying the air outlet. For the adapted signal board, note that the heat dissipation of t
