What is the design principle of rotor and shaft with optional anode?

Is to improve the corrosion resistance and service life of the motor. In the process of motor operation, due to the corrosion of electrolyte, the surfaces of rotor and shaft will gradually corrode, leading to the decline or failure of motor performance. In order to solve this problem, an anode coating can be coated on the surface of the rotor and shaft to form a protective layer to prevent the electrolyte from corroding the rotor and shaft. Select suitable anode coating materials: anode coating materials should have good corrosion resistance, conductivity and adhesion, such as aluminum, magnesium, zinc, etc. Control the coating thickness: the anode coating thickness should be controlled within a certain range. Too thick will affect the rotation balance and heat dissipation of the motor, and too thin will not achieve the protection effect. Ensure coating uniformity: Anode coating should be evenly coated on the surface of rotor and rotating shaft to avoid uneven coating or hollowing. Optimization of coating process: anode coating process should be optimized, such as adopting appropriate coating method and controlling coating temperature and time. To improve the quality and stability of the coating. Optional anode rotor and rotating shaft are common anti-corrosion measures for motors, which are suitable for all kinds of motors, such as fans, pumps and compressors. Besides anode coating, there are other anti-corrosion measures, such as stainless steel materials and anti-corrosion coating. These measures can effectively improve the corrosion resistance and service life of the motor and ensure the normal operation of the motor.
