Motor ro VFD
Motor ro VFD
(OP)
This will be a simple question for you guys on here.
I have a vent fan that is controled by a GE 30HP 480 v Frame 286T motor using a magnetic starter. I was considering slowing the speed of the fan down because too much air is moving in the room. I have a unused Allen Bradley VFD that is rated for 30hp. The question is could the VFD be used with this motor or would a inverter duty motor have to be used with the VFD.

Use it and see if it works OK, some do.
Take prudent steps to protect it as Skogsgura recommended. TCI and MTE make good products for that purpose.
Have the Inverter Duty motor at the ready if this fan is a critical operation.
Separate issue:
If that A-B VFD has been out of service for more than a year, you will need to do a PM procedure on it called "reforming" the capacitors. Search the A-B knowledge base for their recommended reforming procedures (they may spell if re-forming), otherwise there are several good ones out there that search engines can find.
