For over twenty years, ITRC has been involved in projects involving the research on, or evaluation of variable frequency drive motors used for pumping water for irrigation districts, farms, or dairies.  ITRC has also developed detailed specifications for irrigation districts planning variable frequency drive systems, to ensure the appropriate use and installation of VFDs.

Reports available on the ITRC website related to variable frequency drives include:

  • Power quality - measurement and conditioning (R 04-002)
  • Specifications for irrigation districts (R 04-004)
  • Benefits of variable frequency drives (R 02-006)
  • VFD system planning guide (R 02-009)
  • Study of VFD use at Delano-Earlimart ID (R 95-001)
