2.0mm*0.15mm High-Temperature Resistant Enameled Flat Copper Wire
Application:
Why Choose Enameled Flat Copper Wire Instead of Traditional Round Wire?
Characteristics/Advantages and Benefits Higher Slot Fill Factor: Allows for more conductive material within the same winding space, increasing power density and making equipment more compact and efficient.
Excellent Heat Dissipation: The flat wire shape provides a larger contact area with the stator core slots, resulting in a shorter heat conduction path, better heat dissipation, and lower temperature rise.
Excellent mechanical stability: The robust structure after winding allows for better resistance to electromagnetic forces and thermal stresses, especially reducing deformation in high-speed motors.
Reduced eddy current losses (during design optimization): For high-frequency applications, multiple thin flat wires can be wound in parallel or braided in different positions to reduce additional losses caused by the skin effect and proximity effect.
Simply put, enameled flat copper wire excels in any electromagnetic device that needs to handle high currents, achieve high efficiency and power density, and requires a compact design. Its importance is increasingly evident, particularly given the global push for electrification (such as electric vehicles) and energy efficiency improvements.
