Note: Heat six-wire bundles to strip varnish
Objective:
Heating the ends of six wires on a starter motor to remove the electrical varnishes
End Product:
Starter motor
Equipment:
Ambrell 10 kW induction heating system, equipped with a remote workhead containing two 0.5 μF capacitors for a total of 0.25 μF.
An induction heating coil, designed and developed specifically for this application
Materials:
Starter motor with six wire bundles, each wire consists of 3 wires 0.04 in (1.0 mm) diameter each
Temperature:
1202 °F (650 °C)
Frequency:
297 kHz
Testing:
A six-position coil with three turn helical coils at each position is used to simultaneously heat 0.8 in (20mm) length at the end of each copper wire bundle for 2.5 seconds to burn off the electrical varnish.
Benefits:
-
Hands-free heating that involves no operator skill for manufacturing
-
Multi-position coil provides simultaneous heating for quicker production times
-
Complete removal of varnish improves electrical performance of connections
-
Even distribution of heating
