Describle:
The brand new ultra-high-speed brushless vacuum cleaner fan comes with a brushless drive board. The rated voltage is DC28.8V, and the applicable voltage is DC24V-DC30V. The power is constant, and the current changes as the voltage changes to ensure constant power of the fan. NdFeB high-strength magnetic inner rotor and precision aluminum alloy impeller. The speed cannot be tested temporarily, but it is estimated to exceed 100,000 rpm. The current at DC28.8V is 12.8A, the current at DC24V is about 14.6A, and the current at DC30V is 11.8A, the power is 350W, it supports PWM signal to control the speed, and can also run at the highest speed with only one power supply. The suction power is very powerful and it is a brushless fan used in high-end micro vacuum cleaners.
Red line: positive pole of power supply
Black wire: negative pole of power supply
Blue line: PWM
White wire: GND (PWM)
There are three ways to operate this fan:
1. Connect the red wire to the positive pole and the black wire to the negative pole. You can input +5V voltage on the blue wire and connect the 5V negative pole to the white wire. The fan will also run at the highest speed.
2. Connect the red wire to the positive pole, the black wire to the negative pole, and the blue wire to a 50K resistor, and then connect it to the positive pole. The fan will run at the highest speed. In this way, the fan can run normally with only one set of DC power supply. If you need to send For 47K resistance, please make a clear note when taking the photo. If you do not make a note, it will be shipped randomly.
3. The formal connection method is: the red wire is connected to the positive pole, the black wire is connected to the negative pole, the blue wire is connected to the PWM signal (about 5000HZ), and the white wire is connected to the GND of the PWM signal, so that the fan speed can be accurately controlled with the duty cycle.
Note: The brushless DC motor has a drive board. It is strictly forbidden to connect the positive and negative poles in reverse. The red wire is connected to the positive pole and the black wire is connected to the negative pole. If you connect it wrongly, the drive board will be burned out.
