Interesting. It takes 166.187kvA to directly run a 55hp motor.
The 26kva xfmr couldn't quite run a 7hp motor.


Good page, bookmarked!


It might..might run it..but it certainly wont start it.

Put a load on it...poof!

For that sized motor..45 KVA is a requirement

According to the bookmarked site's calc, it takes 166.187kva to run
that motor properly. Where did you get the 45kva number?

The calculator gives 166.187 KVA for a GENSET that will start the
motor. A transformer has the capacity of the grid behind it to provide
the starting surge, a genny needs to provide the peak current all by
itself.

for the 7.5hp motor

We defeated Fascism. We defeated Communism.
We saved Europe in World War I and World War II.
We were willing to do it, glad to do it. We went to
Korea. We went to Vietnam. All in the interest of
preserving the rights of people.

And when all those conflicts were over, what did we
do? Did we stay and conquer? Did we say, "Okay, we
defeated Germany. Now Germany belongs to us? We defeated Japan,
so Japan belongs to us"? No. What did we do?
We built them up. We gave them democratic systems which
they have embraced totally to their soul.
And did we ask for any land? No.

The only land we ever asked for was
enough land to bury our dead."
