In electric vehicles (EVs), magnet wire is a critical component in the electric motor. It forms the windings of the motor’s stator and rotor, enabling the conversion of electrical energy into mechanical motion.
Key Requirements for polymer coating for magnet wires in e-motors (customer specific):
- Extrusion on round or shaped profiles with good concentricity and thickness control
- Excellent dielectric strength at temperature
- Thermal endurance up to 240°C
- Chemical resistance to coolants, solvents, and varnishes
- Extreme abrasion resistance during insertion, bending and wrapping for coil windings
- Favorable adhesion to metals
