Engineering considerations

VFD-compatible motor replacement

VFD-compatible motors require review of the original drive design, harmonic effects, insulation stress, and the ability to operate without changing existing drive settings.

  • Account for THD and high-voltage spike insulation stress
  • Use motor and VFD design data during replacement engineering
  • Witness testing can simulate real operating conditions and load
