Enameled Copper Wire is a kind of cable. The specifications of enameled copper wire are expressed by the diameter of bare copper wire (unit is mm).
The measurement of enameled copper wire specification is actually the measurement of the diameter of bare copper wire, which is generally used for micrometer measurement. The accuracy of micrometer can reach 0.01 mm. The measurement of enameled copper wire specification (wire diameter) includes direct measurement and indirect measurement. The direct measurement method is to directly measure the diameter of bare copper wire. The enameled copper wire needs to be burnt first. The burning method should be adopted.
The enameled copper wire used for the rotor of series excited motor for electric tools has a very small wire diameter, which needs to be burned several times and for a short time when burning, otherwise it may burn off and affect the efficiency. After burning, wipe the burnt lacquer skin clean with cloth, and then measure the diameter of bare copper wire with micrometer. The diameter of bare copper wire is the specification of enameled copper wire.
