varnished wire Specifications and measurement
- Feb 23, 2018 -

Enameled wire is a kind of cable, and the specification of enameled wire is indicated by the diameter of bare copper wire (unit is mm).

Measurement of enameled wire specification, the actual is bare copper wire diameter size measurement, generally used in the micrometer to measure, the accuracy can reach 0.01 mm micrometer, enameled wire specifications (wire diameter) of a direct measurement and indirect measurement method.

Direct measurement

The direct measurement method is to directly measure the diameter of the bare copper wire. It is necessary to burn the enameled leather of the enameled wire first.

Electric tools used in the series motor rotor are very small in line diameter, in the use of fire on a number of short time, otherwise it may burn off and affect the efficiency.

After the burn, the burned patent leather is cleaned, and the diameter of the bare copper wire is measured with a micrometer. The diameter of the bare copper wire is the specification of enameled wire.

Enameled leather can be used with alcohol lamps or candles.

Indirect measurement

The indirect measurement method is to measure the outer diameter of enameled copper wire (including patent leather), and then according to the data of the outer circle diameter of enameled copper wire (including patent leather).

This method does not need to use fire enameled wire coating, high efficiency.

If you can know the specific type of enameled copper wire, then check the enameled wire specification (line diameter) is more accurate.

[small experience]

No matter which method is adopted, you should measure different root number or position 3 times to ensure accurate measurement.

When the difference between the three measurement data is large, it is possible to use the line and analyze it carefully.

No matter which method is adopted, the line should be measured before measurement to ensure accurate measurement.

When the difference between the three measurements is large, it is possible that the line is not straightened.

The direct measurement method is generally used for the measurement of the old line (which is taken off by the burning winding), and the indirect measurement method is generally used for the new measurement, which is convenient and quick.
