Function of Coating on Rotor Surface

Whether from the motor personalized disassembly or production process show can be found, almost all of the motor rotor surface will be coated with a layer of paint, different manufacturers, different types of motor rotor surface coated with paint color and appearance is not the same, today we talk to you about this issue.

From most of the motor production process analysis, the air gap between the motor stator and rotor by the rotor surface of the turning to obtain, after turning, the rotor surface may be due to the production environment or the operation process occurs in the condensation problem and corrosion, and therefore, rust, is an important reason for the motor rotor surface coating.

From the analysis of the industrial aesthetics of the product, the surface coating can increase the visual effect of the product, the manufacturer can set the specific color in accordance with their own characteristics, but also the embodiment of personalized features of the product, but the rotor surface coating should be uniform and consistent, there can be no similar lacquer hangs and other defects that impede the mechanical properties of the motor.

There are also motor manufacturers, for different series of products rotor using different colors of coating, its main purpose is to increase the motor production process of marking the differentiation effect.

In addition to the role of the rotor rust, for the possible existence of corona motor products, the motor stator and rotor surface are coated with corona paint, which is particularly important for the purpose of corona prevention and control, such as high-voltage motors, stator core surface, the winding end surface and the rotor surface of the assembly before the necessary process is to prevent the corona material coating.

In addition to the surface of the rotor, standardized motor manufacturers will be necessary for the motor non-coating surface of the internal cavity coating, the main purpose is to prevent rust, to a certain extent, can also increase the aesthetic effect of the product.

In the production process of any product, from the point of view of cost analysis, we will simplify the process, but from the point of view of product quality assurance, the necessary links can never be omitted.
