Thanks for the technical picture Mark. I understand what you mean about the sizing being based on amps, but I guess the uncertainty comes in while dealing with old Swiss motors like these. I think this one must be from the 60s. Is the 3.2A listed the FLA? If so, will it draw more than 3.2A now...
JST- thanks for the succinct summary; all of that seems to make sense to me. But then Jim thinks a matched HP VFD (1HP in this case) would be adequate. All of the threads I've seen feature both trains of thought but no one ever seems to invalidate each other. Some will just say match the HP, and...
Jim- here is my "breaker box." As you can see, it doesn't even have a main breaker switch that I can shut off, so I really don't want to unscrew this panel and see what's going on. I think some old nyc apartments have these sub panels, where the main breaker is somewhere in the basement.
I will post a picture of the panelboard when I get home tonight. As for the VFD, why is it that some people suggest upsizing based on HP/watts/amps, etc etc. I have tried to google this and search for past threads but I can't really get a clear answer.
Also, just to confirm; the best option...
I guess I should also re-state that wiring directly from the breaker box, or installing new circuit breakers is most likely out of my purview. I do have "access" to the breaker box; it is in my kitchen, and the lathe would be a room over, in the living room (yes, you can laugh at me). I will try...
Thanks to all for the replies, I didn't mean to go awol (or "hit and run" as someone said). I was doing more research on the lathe, the motor, and looking into the suggestions and comments that were posted here. One of the most important things I discovered was that unlike most other...
Hi All,
This is going to be one hell of a long-winded and confusing post, but I could really use any help or advice with my current dilemma: how to power a Schaublin 102 bench mounted toolroom lathe using 110V single phase power. Here is the background: I live in a rental, pre-war apartment in...
