Enamelled flat copper wire is a type of magnet wire with a flat cross-section and an insulating enamel coating on its surface. It is widely used in electrical applications that demand tight winding, high current-carrying capacity, and good heat dissipation.
Enameled Flat Copper Wire Features
High-quality conductor material: High-purity oxygen-free copper rods are used, which are processed into rectangular cross-section conductors through multiple drawing passes, four-roll rolling, and precision annealing processes, featuring low resistance characteristics under high current density.
Insulation performance: It has excellent insulating properties; the insulation layer is resistant to peeling and can effectively prevent short circuits.
High slot fill factor: The rectangular cross-section design increases the motor slot fill rate by 30%-40%. Under the same volume, it can increase the conductor cross-sectional area, reduce winding resistance, and improve motor efficiency by 2%-5%.
Mechanical properties: high mechanical strength, good adhesion, scratch resistance, suitable for winding complex coils.
Applications:
New energy vehicle: Motors made with enamelled flat copper wire have advantages such as high slot fill factor, excellent heat dissipation, and low loss, making them well-suited for powering new energy vehicles.
Industrial high-efficiency motors: Motors manufactured with enamelled flat copper wire are highly efficient and low in noise.
Servo motors: Flat copper wire windings have a compact structure and reduce inductance by 30%, enabling rapid current changes.
