The main raw materials required for the production of DC motors include magnets, windings, copper cores, bearings, and stators. These raw materials must undergo rigorous and precise selection to ensure the motor's performance meets the required quality standards.
Magnets: Magnets should possess high permeability, low hysteresis, high chemical stability, high mechanical strength, and good toughness. During production, they require multiple processes such as cutting and grinding to achieve the desired shape and size.
Windings: High-quality enameled copper wire should be used for the windings, with the wire diameter selected based on actual requirements. During production, the windings are fixed using processes such as painting.
Copper Cores: High-quality copper material must also be used for the copper cores. After cleaning, extrusion, and drawing processes, the copper core achieves the required size and shape.
Bearings: Bearings are one of the most important components of a DC motor. High-quality bearings suitable for the motor's speed and load must be selected.
Stator: The stator of a DC motor must be made of high-performance silicon steel sheets, which undergo multiple processes such as stamping and special machining to achieve the required shape and size.
