Impregnating Resins: Overcoming High Voltage Challenges in New Energy Vehicle Drive Motors

How to deal with the challenges of high voltage in new energy vehicle drive motors, NVH issues under high frequency, insulation damage caused by peak voltage, cold and hot brittleness in high latitude environments, challenges posed by ATF oil environment on insulation, challenges of high slot fill factor on impregnation process, and the environmental protection requirements of beautiful China for impregnating resins."Core Clamp" insulation resin: With the "Core Clamp" series unsaturated polyester imide impregnating resin provided by Hengcheng, it offers low gel temperature, high temperature resistance grade, low thermal weight loss, and environmentally friendly performance through unique design. It is widely used in various applications such as new energy vehicle motors, special industrial motors, high voltage inverters, and servo motors.\n1. The special structural design of the resin ensures high integrity of macromolecules.\n2. The molecular structure is optimized for flexibility, and it can maintain excellent performance under high heat and extreme cold conditions.\n3. The proportion of polar groups such as hydroxyl and waste in the resin molecular structure is minimized.\n4. The low gel temperature improves the filling effect.\n5. It does not contain small molecule diluents such as styrene, methylstyrene, DAP, etc.\n6. The unique combination of material monomers achieves optimal comprehensive performance.\nAdvantages - Features:\n• High filling ability: higher PDIV value and NVH characteristics, gel temperature W100°C.\n• High long-term thermal stability: 220°C*168h, thermal loss does not exceed 5%.\n• Low VOC, flash point >100°C, does not contain styrene and methylstyrene.\n• Can be applied to various impregnation processes, adjustable viscosity, suitable for various immersion, drip impregnation, and roll impregnation.\n• Meets new requirements such as flat wire, high voltage, oil cooling, etc., good long-term high temperature resistance and chemical resistance.\n• High thermal conductivity and good resistance to electrical corona: special products have higher thermal conductivity and better resistance to electrical corona.
