Replacing 3ph 5hp 2sp Pin Router Motor
Replacing 3ph 5hp 2sp Pin Router Motor
(OP)
I have a dilemma. I have acquired an ancient SCMI pin router that has the original, untested 3ph 5hp 2-speed motor in it. It's mechanically sound, but the wiring for the router is a mess, and my personal shop does not have 3ph power. I'm left with two choices. I can either shell out for a VFD which may or may not get this thing running, or I can replace the motor. First, I don't really need 5hp - I'm just going to do some non-production guitar building with this router. I could probably get by fine with 1-3hp. Single phase is a must, and I don't really need the two-speed capability.
The two pics show the current overall motor and the spec tag. The tag tells you most of the story, and I mic'd the shaft at around .68" Can anyone provide any specifics as to possible replacement that would, if not bolt right up, but be comparable in size/configuration/mounting so as to keep fabrication to a minimum?
Any help would be appreciated.

A VFD will allow you to get the MOST out of that motor. It will also you allow you start it softly without resetting half your computers and the neighbors. Seen the price of motors lately? Not sure, but probably about the same price as a VFD.
