There are times when a winding cannot be processed through the burnout oven, so it must be removed "cold." The bond strength of most resins is approximately 8-10 psi (55-70 kPa), which means that a fairly lare coil might have nearly 3,000 pounds (1350 kg) of bonding force with the slot. In those cases, there are some useful tips that can be used to reduce the difficulty in removing the coils. Many of the techniques in this article can be adapted for open-slot, wound rotors and armatures.
