Enameled Wire is a kind of cable. The specifications of enameled wire are all represented by the diameter of bare copper wire (in mm). The measurement of enameled wire specification is actually the diameter measurement of bare copper wire, which is generally used for micrometre measurement. The micrometre precision can reach 0.01 mm. The measurement of enameled wire specification has direct measurement and indirect measurement methods.
A direct measurement method, direct measurement of bare copper wire diameter, need to burn the enameled wire coating, with fire method. The wire diameter used for the rotor wire of the wire motor for electric tools is very small, and it needs to be burned for many times and for a short time during the fire, otherwise, it may burn off and affect the efficiency. Wipe the burnt lacquer with cloth, and then measure the diameter of bare copper wire with a micrometer. The diameter of bare copper wire is of enameled wire specification.
The indirect measurement method is to measure the outer diameter of enameled copper wire (including enameled leather), and then measure according to the outer diameter of enameled copper wire (including enameled leather). The method does not need to burn the enamel of enameled wire and has high efficiency. If you can know the specific type of enameled copper wire, then check the enameled wire specification (diameter) is more accurate.
