1-Phase VFD - Does it have to be derated?

If a VFD is already classified for single phase input, does it still need to be de-rated? Will the motor(specs) shown below, work with the listed VFD specs or do I need to go with a VFD with higher Amp rating? Trying to avoid a step-up transformer and I haven't come across a VFD rated for higher amp rating than what is shown below that can work off a singe phase 115VAC supply.


Thanks.

it should work no derating necessary
from what I see it has a voltage doubler built in
120 1Ph supply with 230V 3Ph output to the motor
what band is it it looks like it may be Yaskawa

I think that’s a Weg part number.

But correct, no de-rating necessary because it is already rated for single phase input. 1-1/2 HP is the upper limit of 120V input, because beyond that the voltage doubler circuit becomes more expensive than a transformer.
