Yep, for the pinnacle of electro-mechanical systems in this regard, you'd probably be looking at early radio sets - for example the Alexanderson alternator - https://en.wikipedia.org/wiki/Alexanderson_alternator - basically a giant multi-polar generator set up to generate current at VLF frequencies.
And those things were horrendously expensive maintenance nightmares.

I am Imagining one of those built to serve a one megawatt turbine ...
It would be the stuff of legends. I imagine the belts would fly off within the first day.
