24V DC Cooling Fan small way to quickly remove rust points

"24V DC Cooling Fan" is used to provide DC power supply: DC motor has a stator and a rotor composed of two parts, there are poles on the stator, the rotor winding, the power, but also form a magnetic pole of the magnetic field, the stator and rotor of the rotor inter has a angle to the magnetic field in the stator and rotor mutual attraction under the motor rotation. Change "iphone下载雷竞技 " brush position, you can change the direction of the angle between the stator and rotor poles, thereby changing the direction of rotation of the motor. Fans used for a long time, there will be a lot of protective cast metal rust spots, difficult to remove, but if you dip some detergent and water applied with a cloth cover, and then dipped in some talcum powder wipe rust spots, and soon will be able to "iphone下载雷竞技 " wipe the rust spots.
