I do wonder about the 3/4 hp motor though just seems under
powered

Sorry for the slow response.
Kind of a newbie, just found the group.
I wonder if this is a single phase motor? The machine was almost certainly 3
phase when built and if someone put in a single phase motor that may have been
all that was handy or perhaps (some installations are VERY tight) because of
the necessarily larger frame size (on a single phase motor of the same hp),
that's all that could be easily stuffed in place?
