Ok, So I'm in the process of restoring my New to Me 1937 SB 9a 409AN. I'm just about finished and purposely saved the motor for the last part. Here's what I found after a complete cleaning of the old motor. It's a Wagner 1/3 hp., single phase, dual voltage, reverse able motor, but its rated at 50cyles. The old motor was full of swarf, the wires were crumbling,and while I've took motors apart before, this one had me puzzled. The motor had four wires coming out and all were black and falling apart. The troubling part was the two were tied together as were the other two. I know from watching Tublecain's videos that 50 cycles is not what we use, so I want to use this 1/2 hp. motor that I currently have on a scroll saw. I would like to use the original drum switch, even though I don't think the motor is reverse able. And do I really need reverse? The Drum switch is a Furnas R-1 rated for 1/2 hp., 110-220 volts AC on a cast iron factory base. I'll post pics of the switch and the motor I plan to use. Can anyone offer any advice? Thanks, Tim.

A 50 cycle motor will work on 60 cycle current. It does not know the difference. The difference will be that the 50 cycle motor will turn 20% faster RPM's on 60 cycles. Yes, I suppose that is over speeding the motor, though often is is just a different motor label for a different market. No, it will not likely burn up or explode by doing that. If there are RPM's listed on the lathe (and the lathe data plate is for 50 cycles!), they will be incorrect by the same 20%. It is your choice on whether you want to go there.

Thanks, Bob for the quick reply! The data plate is for the newer Westinghouse motor I have on a scroll saw. I plan to use it since the old Wagner was full of swarf and upon cleaning found broken wire insulation. Plus the old motor used the oil cups. Would I still be able to use the Westinghouse motor, even though it's not reverse-able and how would I wire it to the drum switch to keep everything looking as near to original as possible?
Thanks, Tim
 
This is the wiring diagram for the Furnas switch I have.
