VFD sizing
VFD sizing
(OP)
Can someone direct me either to a site, previous thread, or good reference book that discusses proper VFD sizing. In searching, I have found various answers all different.
I am sure that I need to base it off the FLA of the motor and not its rating, but I have seen sizing based just on the FLA to two times the FLA. Further, I am sure that there are other considerations that need to be taken into account based on the motor type and application.
If someone could point me in the right direction, I would appreciate it.

RE: VFD sizing
Use that to size the drive. Do not use hp. Use short-term and continuous amps and pick the drive to cover both.
