2UEW 0.28mm Magnetic Winding Wire Enameled Copper Wire For Motor
Our enamelled copper wire has a diameter of 0.28mm and is an example of the high quality material we offer. The wire is coated with a layer of UEW insulation, ensuring excellent insulation properties. Its heat resistance reaches 155 degrees Celsius, providing best-in-class thermal resistance, which is critical for the harsh conditions within motor windings.
·IEC 60317-23
·NEMA MW 77-C
·customized according to customer requirements.
In the field of motor windings, enamelled copper wire plays a vital role in ensuring efficient and reliable performance. When wrapped around the stator and rotor core of a motor, it generates the electromagnetic field required for the motor to operate. Copper's high electrical conductivity ensures minimal energy losses and optimal energy transfer within the motor, resulting in increased efficiency and lower operating costs.
