Compsition of cooling fan

The cooling fan has the following three parts:

1. The control part: Constituted by the hall magnetic switch,transistor and resistor components.Its function is to control the change of the stator coil winding current direction.

2. machine winding parts: motor winding is composed of silicon steel sheet, enameled wire and insulation frame up and down.The function of silicon steel sheet is responsible for the export from poles, in order to determine the strength of the N, S, winding decide the direction of the magnetic field lines, including N, S and control signal, changing winding polarity, promote magnetic field operation, and the purpose of doing work.

3. Fixed field parts: provided by the rubber magnetic fixed, to be used for generate power when rotating.
