Some basic knowledge about Fan: 1, fan blade: is an injection molding, using the PBT+30% glass line class +VO flame retardant produced; 2, bearings: low noise imported oil bearing; 3, the insulation: enameled wire with class B insulation, the temperature of 120 degrees Celsius, 4; connection: lead type (line 25CM). 5, insulation resistance: 500000000000000 ohms or more; 6, high voltage leakage current: 0. 5mA. High voltage 1500V/1 minutes; 7, operating voltage: 110V (voltage range: 85V ~ 125V) 8, operating voltage: 220V (voltage range: 185V ~ 245V); 9, the fan rotation direction: from the direction of the fan blade as counterclockwise; 10, the use of environmental temperature (c): - 10 DEG C 50 C) 11, S: oil bearing service life: the working environment temperature is 40 DEG S: oil bearing) 30000 (H) of short service life, not easy to 24 hours of continuous work for a long time.

Use of the function of:

Range of use: 1, cooling fan cooling fan is mainly to solve the computer, electrical appliances, machine, the problem of heat dissipation of power supply, reduce the working environment temperature of the equipment, prolong the service life of equipment. There are fan air volume using part of the equipment, pressure to complete the function of the equipment, such as air table is to make the ball in the ball table drift by the fan pressure.

Type 2, cooling fan its working principle: cooling fan is mainly divided into two kinds and the DC and AC a) DC cooling fan is the use of DC electric provides power to the DC motor has two stator part and a rotor part, Ci Ji (on the stator winding or permanent magnet), the rotor winding is energized after the rotor is also the formation of magnetic field (Ci Ji), an included angle is formed between the stator and rotor of Ci Ji, the rotor magnetic field (between N and S poles) mutual attraction work.
