IPS IntegraCoil – Checklist

IntegraCoil high-voltage Rewind Checklist

IntegraCoil is our high-voltage B-Stage Hard Coil rewind for stators from 6.6 kV to 15 kV. It is designed for a 25+year lifecycle providing winding reliability for stators that need to be rewound on-site, or are too big to fit into a VPI tank. We’ve installed it in over 500 electric motors and generators over the last 25+ years, in industrial applications throughout North America. Use this comparison chart to make sure that you’re getting the best and most reliable high-voltage B-Stage Hard Coil stator rewind for your electric motor or generator.
