So a friend asked me a question and I did not have an answer for him but it did intrigue me.

If you have a 3 phase 460v motor (without a VFD or ECM) and you only give it 220 (also 3 phase). Will it cause any issues?

I guessed that it would work but wouldn't get you full power, but I told him that was just a guess and I would ask to see if anyone knew.

That's what I figured. He shopping for components and was wondering about compatibility between components.

Overall it sounds like a waste of power.

It's not a waste of power. The power used and the output are reduced by about 77%. The motor will likely be much larger and heavier for the output it produces at the lower voltages than a 220V three phase with that same output.
