Rewinding

  • Diagnostic Electrical Tests and Certification: circuit resistance, insulation resistance, polarization index and absorption, Surge and Hi Pot
  • Core Loss Test
  • Redesigns and/or evaluation of windings utilizing specialized Software
  • Comparison of windings: Manufacturer's design to databases.
  • Form-wound windings (coils imported from USA)
  • Installing of INVERTER DUTY insulation system (Operation VFD)
  • Design and manufacture of slot wedges and locking systems
  • Installation of temperature sensors (thermistors, thermostats, RTDs)
  • Vacuum Pressure Impregnation (VPI) in resin
  • Installation of heating resistors and other accessories
