Note: Wire stripping (varnish removal)
Objective:
Heat wires to burn off the varnish coating
End Product:
Copper wire bundle
Equipment:
Ambrell 7.5 kW induction heating system equipped with a remote heat station, containing one 1.00 μF capacitor.
An induction heating coil designed and developed specifically for this application.
Materials:
Flat copper wire bundle of wires with a rectangular cross-section of .025 in2 (.0635 cm2)
Temperature:
1300 °F (704 °C)
Frequency:
204 kHz
Testing:
An eight-turn helical coil is used to generate the desired heat pattern. The coil has a 0.62 in ID. An individual wire is inserted and heated to burn off the varnish for 5 seconds. Larger cross sectional areas require a longer heat time or higher power. After the heat cycle, each wire is removed from the coil and allowed to cool at a natural rate.
Benefits:
Compared to mechanical scraping, induction heating is faster and highly repeatable for consistent results
