Original Japanese nidec brushless high-power vacuum cleaner fan
Brand new original, very beautiful workmanship, built-in high-power brushless drive
The power supply can use 5-6S power lithium battery
The nominal voltage is 21.6V, the actual test can be used in the 15-25V range
Rated power 370W, the maximum power under measured 24V voltage is more than 400 watts
Just like the small engine of a model airplane, it is very violent and shocking.
This fan is simpler than previous brushless motor drives
The motor supports 18khz PWM signal speed regulation
PWM speed linearity is very good
The minimum current can reach 500ma
Can also be connected to a 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 signal blue and green are connected to 5V, it is the highest speed operation
The definition of wiring is marked in the introduction drawing.
The fan supports 15-25V wide voltage operation
15V maximum current can reach about 10A
The maximum current of 25V can reach about 18A.
The fan weighs 282 grams
The price tag is the price of a fan motor.
