S/G vfd check

[HSC ///]

I’m in France with an existing mill powered By an ATO vfd. 220 in to 3 ph 380 out

Here’s the motor plate of the surface grinder I’m getting. It’s 3 ph 380

Will my existing vfd work for the new s/g?

As another vfd is about $300+ I’m thinking to use the rotary switch S Scaniaman referenced here

It should work fine.

 

[Scaniaman]

Yes that should work out just fine.

PS I will email you the switch I have used, four of them so far and they work great

Make sure you're matching voltage on VFD output and Motor input

Since you're euro, it's making sure your dual voltage motor is set for 380
The inside of that motor plate usually tells you how, which wires get grouped together.



For the North Americans, it's usually having a VFD output do 240 three phase and the motor being wired to match.

I got caught out buying a cheap three phase motor early on because it was 440 -not dual voltage, I didn't know any better.
