Electrical question
#1
I have been patiently waiting to buy a RPC to drive a 3 phase 440v lathe. It's a 1986 Smart & Brown 1024 VSL. There are a number of personal issues I have been dealing with for the past coupke of years that has kept me from getting serious about getting this lathe up and running. I won't bore you with all the details but suffice it to say those issues have resolved themselves. It occurred to me that I might be able to rewire the motor to run on 220v 3 phase and then use a VFD instead of the RPC and step up transformer I was planning on. So tonight I took the backplate of the lathe and got a couple photos. The motor was built by Brooks and Compton but of course I can't find any information on the Internet regarding this particular serial number. It's a 3hp motor and from what I can tell from the website Brooks & Compton the motor might be dual voltage rated? I am also of the understanding that I "should" be able to run a 50 hertz motor on 60 hertz with no real issues?

I'm going to contact the manufacturer and see what information I can get but was hoping some of you might give me your thoughts on my plan. 

Here are a couple of photos.
