Store and maintain in the correct way to extend the service life of the DC cooling fan. The following high-quality fan manufacturers will provide you with detailed maintenance methods for DC cooling fans:
1. During the operation of the DC cooling fan, if any abnormal sound is found, the motor is severely heated, the casing is charged, the switch trips, and cannot be started, the fan should be immediately stopped for inspection. To ensure safety, maintenance is not allowed during the operation of the fan. After maintenance, a trial run should be carried out for about five minutes to confirm that there are no abnormalities before starting and running.
2. DC cooling fans should be stored in a dry environment to avoid moisture on the motor. When DC cooling fans are stored outdoors, protective measures should be taken. During storage and handling, it is necessary to prevent the DC cooling fan from colliding to prevent damage to the fan.
3. The fan can only operate under completely normal conditions, while ensuring sufficient capacity and stable voltage of the power supply facilities. It is strictly prohibited to operate without phase. The power supply line must be a dedicated line and temporary lines should not be used for long-term power supply.
4. The DC cooling fan should be kept clean and tidy in the use environment, with a clean surface. There should be no debris at the inlet and outlet, and dust and other debris inside the fan and pipeline should be regularly removed.
5. According to the environmental conditions of use, bearings should be supplemented or replaced with lubricating grease periodically (motor enclosed bearings do not need to be replaced with lubricating grease during their service life). In order to ensure good lubrication of the DC cooling fan during operation, the frequency of refueling should not be less than 1000 hours per time for enclosed bearings and motor bearings. Fill one-third of the inner and outer rings of the bearings with zl-3 lithium based lubricating grease, and it is strictly prohibited to operate without oil.

The working principle of cooling fan
Using the principle of electromagnetic induction, the fan uses the Houle induction module as a synchronous detection device, controls a set of circuits, switches the winding electrification sequence, and generates a rotating magnetic field, a mechatronics engineering fan for electronic commutation. The cooling fan has obvious advantages in the aspects of wide speed range, light weight, environmental protection and energy saving, controllability, reliability, environmental endurance and economy, etc. , dominate. The cooling fan is powered by direct current. The DC motor is composed of stator and rotor. The stator has a magnetic pole (winding type or permanent magnet type) , while the rotor has a winding, after the staff electrified it, the rotor also forms a magnetic field (magnetic pole) , there is an angle between the stator and the rotor magnetic pole, in the stator and rotor magnetic field (N-pole and S-pole) under the mutual attraction, is the motor rotation. The cooling fan technician told us to change the position of the brush, you can change the direction of the rotor-stator magnetic pole angle (starting with the stator's magnetic pole, the rotor's magnetic pole is on the other side, and the direction from the rotor's magnetic pole to the stator's magnetic pole is the direction of the motor's rotation) , after this operation, the rotation direction of the motor can be changed.

How to choose the right cooling fan or other cooling fans
The design engineers of all motor automation equipment and electronic products that require the use of cooling fans for heat dissipation must determine the air volume required for a specific system's heat dissipation
What is the difference between a DC fan and an AC fan?
The working principle of a DC cooling fan: It is driven by 4102 DC voltage and electromagnetic induction. 1653 converts electrical energy into machinery to drive the fan blades to rotate, relying on the coil and IC to continuously switch, and the induction magnetic ring drives the fan blades to rotate.
Bearing - an important component in the cooling fan
Bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy.
AC fan, mainly used for cooling electronic products, is a universal small AC fan. Widely used in the home appliance industry, mechanical industry, manufacturing equipment industry, and other products with ventilation and heat dissipation requirements.
