Insulating Electric Motors: VPI or Varnish Dip?

May 19, 2016

VPI (Vacuum Pressure Impregnation) is a process that is a technological step forward from varnishing electric motors. The old dip and bake (in varnish) method of “insulating” motors is replaced by the VPI process for specific reasons: Harsh Environment Improved Efficiency (through better heat transfer) Improved Mechanical Winding Design When electric motor repairs proceed as …
