Graule ZS135 Radial Arm Saw voltage question

[Brian Holcombe]

Recently purchased this Graule at auction in Germany, it went for cheap but import and shipping resolved that bargain aspect pretty quickly.

I'm rather unsure of what the voltage is, the tags seem to be giving mixed signals. I wrote the company, but I expect it'll be a while before they provide any insight.

I take this back, that's a pretty damaged plate.

Ingress protection (IP) is 7,5a/400v

single phase is 230
three phase is 400

Interesting, I want to say I've seen some of these machines market 230v/380v so I'm not sure they have always been divided up into 1ph/3ph

[mike stenson]

Since the EU uses wye, it's 230 L(x) to neutral and 380 L1, L2, L3. I've seen a lot of equipment that can do either.

Mike, the machine tag on this is gone, likely from having the dust chute replaced at some point.

Here is a similar listing for a similar machine (not the same) which shows dual voltage, just like you are saying.

Im tempted to plug it into 230v/60hz 3ph and see if it has full power, but I may wait a few days and see what kind of info I can dredge up.

At worse case, it'd be like it lost a couple legs. Safer as trying to shove 380v down a circuit configured for 230

The one you posted is the same type at least. What does the power whip connections look like in the box?

[Brian Holcombe]

It’s starting to occur to me, and you and Edward have suggested this, that 230v in Europe is only single phase. If that’s the case, I would think this might need a capacitor, but rather I would just run a vfd and leave it at 380v.

Im going to open up the box soon and take note of how it’s connected.

Europe is also 50hz, here in the states it's 60hz.
I think you're going to need some type of step down transformer.

[Brian Holcombe]

I’m confused on the input voltage, If I can get it running on 230v three phase, I plan to use a VFD and will plug in 50hz. If the swap to 230v requires single phase, then I will find another path forward.

Transformers don't impact frequency.

Correct, 230v is single phase. It's a single line (brown generally, may be black or grey) and neutral (blue).

Hate to be obvious but single phase will only have two hot wires with a ground wire. Three phase will have three hot wires with a ground.
In Europe I think ground is often green with yellow stripe. Meter it out to be sure.

Single phase delta will. Europe uses, the vast majority, single phase wye. Which is a single hot and a neutral.

Grounds are indeed green/yellow.
