Violent metal ducted fan in very good condition, with original drive, perfect refit with potentiometer for large-scale speed regulation. The motor is a 3-phase brushless motor, the coil is wound with multiple strands of fine copper wire, imported nsk ball bearings, is a German PAPST double ball brushless motor,
The motor is driven by the original belt, and the workmanship is very good. It is produced by Nidec in Japan, which is much better than the ordinary ESC. The modified speed regulation only needs one potentiometer and one resistor to adjust the speed in a wide range. The low speed is quiet like a virgin, and the high speed is like a rabbit.
The original input port cannot adjust the speed, only the high and low speed 2 gears can be switched, the high-speed current is 5a, the low-speed current is 2.2a, and the modified current is 0.3a-15a stepless adjustment. The fan is complete with a casing and weighs 1.2kg.
Modification is risky, the wrong electronic components are easily burned, and the fan is sold without warranty. After all, the brushless motor is controlled by electronic circuits. A little mistake is easy to break. Please understand, each fan is powered on and tested before delivery. . ! ! !
