The performance of the aluminum wire motor will continue to deteriorate over time. Not only will its lifespan be greatly shortened, but it will also be more susceptible to oxidation after welding, causing early corrosion and falling off, resulting in poor contact, or increased resistance, which can easily cause heat and even fire.

[0025] The plastic-sealed stator of the above-mentioned washer-dryer motor is plastic-sealed with BMC thermosetting material, which has a long service life and is corrosion-resistant and moisture-resistant. BMC (DMC) material is the abbreviation of Bulk (Dough) molding compounds, that is, bulk molding compound. It is often called unsaturated polyester bulk molding compound in China. Its main raw materials are GF (chopped glass fiber), UP (unsaturated resin), MD (filler calcium carbonate) and various additives that are fully mixed to form a bulk prepreg. Because BMC bulk molding compound has excellent electrical properties, mechanical properties, heat resistance, chemical corrosion resistance, and is adaptable to various molding processes, it can meet the performance requirements of various products. Bulk molding compound (BMC) is a thermosetting plastic in which various inert fillers, fiber reinforcements, catalysts, stabilizers and pigments are mixed to form an adhesive "putty-like" composite material for compression molding or injection molding. Bulk molding compound (BMC) is highly filled and reinforced with short fibers, with glass fiber reinforcement accounting for 10% to 30%. The length is usually between 1 / 32 inch and 1 / 2 inch (12.5mm). The material has good heat dissipation performance; the protection level reaches IP43.

[0026] Depending on the final application, the formulated composite materials can be precisely sized, flame retardant and anti-tracking, with high dielectric strength, corrosion resistance and stain resistance, excellent mechanical properties, low shrinkage and stable color. Bulk molding compound (BMC) has excellent flow characteristics and insulation and flame retardancy, and is very suitable for various applications requiring precise details and dimensions. The material is available in 75 colors and can withstand powder spray or water-based paint.
