Default 5 hp 3 phase motor to a 3/4 hp single phase..?

"Paul" wrote in message ...
Well I gave up on finding a cheap 3 phase motor today and bought a new one.
I paid $172 out the door with a 2 year warranty (5 hp). Its a Chinese model
but hey
they company I bought it from said it was good and all the mining companies
around
here use them all the time. So I guess I will find out! At some point
during today I
ran out of "I am willing to drive around forever to find...cheap." Anyhow
next in
line I've got to connect this to a pony 3/4 horse single phase motor that I
have...
to use as a starter. Any ideas? The 5 hp motor has a 1 1/8" spindle and the
other
has a 5/8" spindle. I think I might try to make a sleeve to attach them end
to end.
Other than that pulleys perhaps? But that might take up a bunch of room.
Anyhow that's where I'm at.

Reno, Paul



For a 5 horse motor, ALL you need to get it started is a small
starting capacitor... About $5.00 worth. New.
Someone else will chime in, but I would go with about 500 mfd. 370 volt.

It's not too critical. The start button adds the starting capacitor.
When you take your finger off the starting button, it is no longer
connected.
The 5 horse motor wil snap up to speed. No sweat. Really.

Forget the pony motor.
