surface grinder 3 phase with phase convertor

[HSC ///]

I happen to have a phase converter in stock, I think it handles 1-3 HP
If I see a surface grinder that I like and it's 3 phase, I want to use the phase converter I have to wire it up.

Question - what is the practical implication of using a phase converter here to me as the user.
Are their power draw considerations?
Will there be any loss of performance with the phase conversion?

I think this surface grinder is a 1/2 HP , so I'll have to get the correct phase converter?

What kind of phase converter, static or rotary or "phase perfect" solid state?

What kind of phase converter, static or rotary or "phase perfect" solid state?

it's a static
the maker says - "Because a static converter isn't a true 3-phase converter, your motor will only have around 2/3 of its rated horsepower."

I believe a static is ok for a surface grinder application, do you think I need a rotary?
thoughts?

No, a static is fine, it just won't develop full power and the motor may not run as smoothly, but it should work okay. I ran a surface grinder off a static for years. The amp draw isn't noticeably different and the converter doesn't really consume power itself. All a static converter does is start the three phase motor which then continues to run on two of the three windings.

I have a phase o matic static converter running my surface grinder. its a 3/4hp motor and the converter is rated the same as yours. I don't know enough about surface grinding to know how good a finish I can get with it but I do know it works. It spits out enough power that I've burnt steel and also sent a few pieces flying across the shop
