Special enameled wire for new energy vehicle drive motor

In the era of explosive growth of new energy vehicles, the performance of the drive motor directly determines the vehicle’s endurance and reliability. However, harsh working conditions such as high temperature, high frequency vibration, and high current impact place extremely high demands on the temperature resistance, insulation strength, and conductive efficiency of the core material of the motor – the enameled wire. Traditional enameled wire is prone to aging and breakdown, becoming an “invisible shortcoming” that restricts the energy efficiency of the motor.

Flait Aluminum produces special enameled wire for new energy vehicles, with 155 class heat resistance, low-loss copper core, and environmentally friendly technology to provide long-term and stable protection for the drive motor!

Three major challenges of drive motors

◆ High-temperature breakdown risk: The continuous operating temperature of the motor can reach above 150°C, and the paint film of ordinary 130 class enameled wire is prone to cracking, resulting in short circuits between turns and motor burnout.

◆ Energy efficiency loss: For every 10°C increase in temperature rise, the resistance loss increases by 5%, and the cruising range decreases by 3%-5%.

◆ Environmental compliance pressure‌: EU REACH, China RoHS and other regulations require enameled wire to be halogen-free and low in VOCs emissions, and traditional solvent-based coatings are facing the risk of being eliminated.

✅‌Solution‌: Choose enameled wire for new energy vehicles, with a temperature resistance of 155℃ (H grade), and a 3-fold increase in insulation life, which helps the motor meet both energy efficiency and environmental protection standards!

Core advantages of 155 class enameled wire

• ‌ 1. High temperature resistance + corona resistance, long-term stability of the insulation layer‌

◆ Material upgrade‌: Polyesterimide + nano-alumina composite coating, resistant to high temperatures of 155℃ (short-term 180℃), corona resistance life＞100 hours (national standard ≥50 hours).

◆ Process guarantee‌: Six-layer precision coating process, paint film thickness error <±2μm, breakdown voltage ≥10kV (industry average 8kV).

• ‌ 2. High conductivity + low loss, battery life increased by 10%‌

◆ Copper core purity ≥ 99.99%‌: resistivity as low as 0.01724Ω·mm²/m, conductivity efficiency increased by 15%.

◆ Compact coil design‌: supports winding with smaller wire diameter (0.2mm-2.5mm), motor volume reduced by 20%, power density increased by 30%.

• ‌ 3. Environmentally friendly process, worry-free global certification‌

◆ Zero halogen + water-based paint‌: VOCs emissions <5mg/m³, certified by UL, IEC 60317 and GB/T 6109, and compliant with EU REACH regulations.

◆ Recycling‌: Production waste recovery rate > 95%, helping automakers achieve carbon neutrality goals.
