i need a 1ph 240 to 3 ph 240 converter for the new lathe. decided it be easier to do than swap the other motor. a cheap one is fine for a lathe.
like this?
its a 1.5hp motor on the lathe. i have a 1hp 220 1phase motor. sounds like same power would be given from both with a static converter, so 48$ is way easier than mounts, pulleys and hassel. plus, i think it has a reverse switch on the late also.

240V 3PH delta? aka no neutral. makes a huge difference on phase converter.
-
say what?
-
that box makes my 1.5 hp motor run on single phase at 1hp? fine for a rotary lathe.
that was my take
-
Light to moderately loaded motor loads only - Wye wound (2/3 capacity), Delta wound (1/2 capacity)
Intended for wye wound motors. Some delta wound motors may operate but will produce 50% of their nameplate HP.
-
ok so .75hp instead of 1hp worst case.
would the tag say how its wound? its probably a 1960's motor

There's what I was looking for
A static phase converter is a startup device for three phase motors running on single phase power. They generate three phase power only long enough for the motor to start up, not continuously like a rotary phase converter would. Once the three phase motor has started up, the static phase converter circuitry disconnects itself, and the motor continuse to run on single phase power. Two of the three windings receive power during running, so horsepower output is reduced to between 2/3 to 1/2 of the rated motor horsepower. For example, a 20 HP motor will start with the power of a 20 HP motor but run as a 10 HP motor.

ya, i under stand that. they just provide a weak 3rd leg. fine for mill or late with lots of spinning mass.
clicked by it now!

If your running for long periods of time, you will most likely burn up the motor.
I've seen static with additional capacitors to run continuous 3ph, but these are not doing that.
I'd go with a rotary converter, only $100 for 1-3hp.
-
they provide no 3rd leg after power up.
-
i saw more like 350$ for a 3hp rotary

Requires a motor to work correctly?

This is whats needed,

right you are
-
jeff runs his lathe and mill on a static converter fine, ill give it a try for 48$

agreed
