New stock Japanese nidec brushless motor micro turbine fan, built-in drive, support PWM speed regulation, originally used in the vacuum cleaner fan host in the sweeper, this motor should be rated at 15V DC, the measured DC 5-15V can run, PWM The speed control signal is a 5V 10-20Khz duty cycle signal for speed control. If you only need to run a PWM line at the highest speed in series with a 10K resistor connected to the positive pole of the power supply, the inner fan blade is a turbine high-speed blade, which drives balance correction. The diameter of the impeller 60mm.
Note that the color of the supplied terminal wires is not correct. Be sure not to connect the positive and negative poles incorrectly. The positive and negative poles of the brushless motor power supply cannot be reversed, otherwise the drive will be burned out. The motor power supply and the PWM speed control signal must be connected simultaneously to turn , first turn on the power of the motor and then connect to the PWM speed control signal, the motor will not turn. After the motor runs, do not adjust the speed to the minimum until the motor stops, otherwise the power needs to be restarted before it can turn.
The measured air volume of the fan is still very good. This one has an imported outlet and is suitable for retrofitting a turbo fan, a sweat cooling fan for summer clothes, a barbecue blower, etc. Under 12V voltage, the air outlet is 10CM away from the face. Do not open your eyes, individual tolerance is different, the test is for reference only, the specific video also has the actual measurement introduction for reference, the test suction is also good, blocking the suction port can lift a jar of about 120 grams.
The speed of the motor test under different voltages is as follows, the load current is as follows, the power can reach 36W under the voltage of 15V, the motor will heat up obviously, and the specific continuous durability needs to be tested by yourself.
5V voltage: current 0.6A, 3W, speed 7000 rpm.
8V voltage: current 1.1A, 9W, speed 11000 rpm.
12V voltage: current 1.8A, 21W, speed 15000 rpm.
15V voltage: current 2.4A, 36W, speed 18000 rpm.
The fan weighs about 80 grams.![](https://ae01.alicdn.com/kf/S3874158a29af4776b1209c962ffb3233a.jpg)
