Description

The new DC brushless worm gear fan, rated voltage is DC5V, the applicable voltage is DC3V-9V, it is estimated that the original humidifier blower, the volume is small, but the air volume is OK, especially when pressurized to DC9V, the air volume is really good. of.         This batch of fans is a brand new original, one is 450 PCS, but it feels like this is a relatively low-end blower, the packaging is not very good, please understand the buyer friends understand.         Note: For DC brushless motor, the red wire is connected to the positive pole, the black wire is connected to the negative pole, and the positive and negative poles are not connected incorrectly. If the fault is connected, the driver board may be burnt out.

  Note: The red wire is connected to the positive pole, the black wire is connected to the negative pole, and the positive and negative poles are not connected incorrectly. If the fault is connected, the driver board may be damaged.

Blower line length: 140 MM   Weight : 30 grams   The following parameters for measuring different voltages are as follows:   DC3V current: 0.16 A impeller speed: 2060 rpm   DC3.7V Current: 0.2 A Impeller Speed: 3040 rpm   DC4.2V Current: 0.23 A Impeller Speed: 3360 rpm   DC5V current: 0.28 A impeller speed: 3790 rpm   DC6V current : 0.33 A impeller speed : 4220 rpm   DC9V current : 0.48 A impeller speed : 5400 rpm   The higher the voltage of the fan, the higher the speed of the impeller, the greater the wind power, the greater the power, but the higher the current, the faster the sound, the larger the sound, and the more prone to heat.   When DC3V: The air volume is soft and the sound is very quiet.   At DC3.7V, the air volume is larger than 3V, and the sound is very quiet.   DC4.2V, the air volume is OK, and the sound is quiet.   At DC5V, the air volume is quite good, but the sound is larger than 4.2V.   At DC6V, the air volume is quite good, but the sound is also a little bigger.   At DC9V, the air volume is very good, but the sound is not quiet.          The rated voltage of this batch of fans is DC5V, so the suitable voltage should be DC5V or DC6V. The pressure is up to DC9V. It is overpressure, the wind is hot, but we let it work continuously for half an hour, the motor is still normal. Working, it should also be the allowable voltage of the fan.
