Introduction:
Original Japanese Nidec brushless high-power vacuum cleaner fan, brand new original, very beautiful workmanship, built-in high power
brushless drive, 72000 rpm high-speed motor, measured maximum power of about 400 watts under 24V voltage, just like the
small engine of a model airplane ducted aircraft. Very violent and shocking.
Another model has a nominal voltage of 25.2V and a rated power of 400W. It can use 57S power lithium batteries, and the actual
test can be used in the range of 15-29V.
This fan is simpler than the previous brushless motor drives.
The motor supports 18khz PWM signal speed regulation. The PWM
speed regulation linearity is very good. The minimum current can be about 500ma. It can also be connected to an external
potentiometer to support stepless speed regulation. , Adjusting linearity is not as good as PWM.
If you need to run at the highest
speed directly, as long as the blue and green signals are connected to 5V, it is the highest speed. For the wiring definition, see the
introduction diagram and have an annotation. Netizens feedback the signal line green and blue together in series. The positive pole
of the 100K resistance direct power supply can also start and run at the highest speed, and the shop owner can also measure it.
Do
not connect the resistance to power the high voltage direct signal line.
The 21.6V 370W fan supports 1525V wide voltage operation, the maximum current of 15V can reach about 10A, the maximum
current of 25V can reach about 18A, and the 25.2V 400W style is about 2A at the same voltage, but it can be driven at a higher
voltage, so the power is a little larger than 370W , Support a wider voltage 15-29V.
