The stator and rotor core of motor is one of the important parts of motor, and its quality will directly affect the overall technical performance of motor. Therefore, the overall quality of the motor core is also very important. As a professional supplier of motor iron core antirust oil, Jiaweiao advises customers to do a good job in surface treatment of motor iron core. Using antirust oil has become one of the more economical ways, thus prolonging the life of motor iron core. The stator and rotor iron core products of the motor are naked, and the paint of the stator iron core is not in place, which easily leads to the surface rust of the stator and rotor iron core of the motor. In addition, in the transportation process, due to the relatively long transportation time and the influence of environmental weather, the products will rust, which will affect the appearance quality of the motor surface and reduce the performance of the motor, and can not meet the quality requirements of high-end customers. 18 1-2963-9559
? Usage and technology of antirust oil for motor core: Before applying antirust oil, certain pretreatment is needed, so that antirust oil can play a greater role. Before applying antirust oil, keep the surface of motor core clean. Under normal circumstances, the section of the newly punched motor core is bright and has no rust spots, so it can be directly sprayed with special antirust oil for motor core and packed in a closed container or package. In particular, the laminated riveted iron core processed by high-speed punching machine is taken out with gloves and put into the package for timely spraying. If the motor core is machined in a single piece, the iron core that needs to be riveted by hand in the later stage will be exposed to air for a long time, and it will be put on hold for a long time, even after aluminum casting, so it is necessary to clean the surface of the motor core first. After pretreatment, dip-coating or spraying antirust oil.
? Immerse the cleaned motor iron core parts in liquid antirust oil, and when the oil is completely coated on the metal surface to a certain oil film thickness, take it out and drain it, and the dipping is completed. This method is most suitable for oil sealing of a large number of small motor cores and micro motor cores, such as electric tool motor cores, servo motor cores, stepping motor cores, channel motor cores, shielded motor cores, household motor cores and other small iron core products. Large iron cores can also be dipped as a whole. Not suitable for products with coated surface. The front of the iron core itself is coated, and the oil seal section will have a good effect. After brushing the motor core antirust oil with a brush, apply it to the clean motor core surface. This method is suitable for all products, especially for products with side coating or rust-proof cross section. For example, in the packaging process of EI silicon steel sheet, EI silicon steel sheet (EI silicon steel sheet) should be packaged with the legs of E silicon steel sheet facing upward as far as possible. When the plastic film is put into the package at one time, the E-type silicon steel sheets should be stacked neatly, and the antirust oil can be evenly coated with a brush. For special-shaped silicon steel sheet products with complex structure and many holes, the hidden parts or corners must be repeated many times, and one layer must be brushed every yard, and so on. When the number of silicon steel sheets in the box reaches the standard, the plastic film effectively covers the surface of the iron core and the carton is closed. 18 1-2963-9559
? In the process of painting, the coating should not be too thick, and the iron core should be evenly painted vertically and horizontally to avoid the corrosion of the battery and the thick coating on the surface of the iron core caused by uneven coating thickness. Prevent corrosion caused by brush leakage.
