On-board drive system

Pure electric vehicles are powered by on-board battery packs, and the range is affected by the efficiency of the motor. Due to the high power density requirements of electric vehicle motors, heat dissipation is also a primary problem for designers. The motor generates a large amount of heat during operation, and the heat in the stator is conducted from the core to the chassis by the heat-conducting material, and the chassis disperses the heat to the environment through the water-cooled water channel or the fins on the surface.

The gap between the motor end winding and the chassis is potted with a thermally conductive material - thermally conductive potting compound, which remains solid after heating and curing and has good thermal conductivity and insulating properties.

Thermally conductive spacer BN-FS300 is in direct contact with the cooling plate and conducts heat out through the cooling plate and cooling disc to achieve good heat dissipation.

Flame retardant insulating sheets BN-FP, BN-ZD16 build additional heat path between the key heat generating parts of the motor and the cooling shell to strengthen the heat dissipation of the motor.

Thermally conductive sealant BN-RT200 series is used for motor casing sealing, bonding, insulation, with high and low temperature aging resistance, UV resistance, good electrical insulation and other characteristics, through the absorption of air moisture room temperature curing for electronic components to provide insulation, shock, moisture and waterproof protection.
