0.28mm 0.3mm Class155/180 Enameled Copper Winding Solid Conductor Insulated
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.
