Enameled copper wire is a type of wire that consists of a pure copper conductor wrapped in an insulating lacquer layer. The conductor is made of high purity copper with good electrical conductivity and mechanical strength. The insulating varnish layer is usually made of polyamideimide (PI) or similar material, which has good insulating properties and heat resistance.

European-style motor windings refer to motors manufactured under European standards, such as AC motors and asynchronous motors. Enameled copper wire is widely used in the windings of these motors to conduct current and form electromagnetic coils. Motor windings require wires with good conductivity, insulation and heat resistance to ensure efficient operation and reliability of the motor.

The insulating varnish layer of enameled copper wire has good insulating properties and can effectively isolate the current between the wires to prevent leakage and short circuits. The insulating varnish layer is also able to resist the influence of external environmental factors such as moisture, chemicals and mechanical stress.


The enameled copper wire used in the windings of European motors usually adopts a high-temperature and heat-resistant insulating varnish layer, which is able to withstand the high-temperature environment when the motor is running, and the insulation level of the enameled copper wire is selected according to the working temperature requirements of the motor. Common insulation classes include Class B (130 degrees Celsius), Class F (155 degrees Celsius) and Class H (180 degrees Celsius). Choosing the proper insulation class ensures that the wire will not be damaged by overheating or cause a safety hazard when the motor is in operation.

The production and use of enameled copper wire for European-style motor windings usually follows relevant standards such as the International Electrotechnical Commission (IEC) and the European Standard (EN). These standards specify wire dimensions, insulation thickness, electrical properties and quality requirements to ensure the safety and performance of motor windings.

When selecting enameled copper wire for European motor windings, evaluation and selection should be based on specific motor design requirements, operating temperature and current load. Consultation with the motor manufacturer or engineer is recommended to ensure that the proper enameled copper wire is selected to meet the motor winding requirements.
