Small Cooling Fan function uses

1, "Small Cooling Fan" in the use of: cooling fan is mainly to solve the heat problem computers, electrical appliances, machinery, power supply, reducing the operating ambient temperature of equipment, extend the life of the equipment. There are some devices utilize a fan of wind, air pressure to the complete functionality of the device, such as air tables is to use the fan pressure on the ball so that the ball can drift countertops.
2, "Small Cooling Fan" type of extremely works: two main types of cooling fans and DC and AC a) DC cooling fan is to provide the use of a DC power supply: DC motor has a stator and a rotor of two parts, "Small Cooling Fan"There poles (windings or permanent magnet) on the stator and rotor windings, the power, the rotor has a magnetic field (magnetic), between the stator and rotor poles at an angle in the stator and rotor magnetic field (N and S poles between) the mutual attraction of the work under the operation.
