Wrong Rpm Motor On My Wards Version Logan 200

The Frame Size should also be on the motor nameplate. One spec for the 56 frame is a 5/8" dia. spindle. It also specifies the case diameter, that it has a saddle type mount on the side, and what the mounting hole pattern is.I don't recall whether in the case of the motor being capacitor start it specifies where the capacitor is (top or side).
 
Is there anyway to lower the rpm to 1725 by adding an electrical device internally or externally? Please keep in mind I know almost nothing about electricity.
 
hi Bama,
your best bet is to see if you could get a smaller pulley(1/2 of the size on the motor now), the motor would spin more times per minute- giving the desired speed.
 
Bama,

There isn't any economically practical way to run a 3450 RPM single phase capacitor start motor at half speed. I don't know what section motor belt it has but it's unlikely that the motor pulley is large enough that one half that diameter wouldn't be too small for the belt. You might get away with putting the smallest rated pulley on the motor and putting a larger one on the countershaft. But as I think that I already said, your best course of action is to put the correct motor on it.
 
Isn't that pulley on the motor a step pulley, like the similar Logans?? I do not think you will find a pulley with 1/2 the circumference. And unless you find a step both 1/2 original ... you will loose 1/2 of your speeds. Get the proper motor and set it up correctly.
 
I think I have been convinced to go with the correct rpm motor. I checked Grizzly today and I can get a 3/4 hp shipped for around $130. I will be posting on local, Jacksonville, Fl Craigslist, a trade or purchase for a 1725 rpm motor. Thanks for the education and advice.
 
I think that is the smart way to go ... can you tell? :bull: Either a 1/2 or 3/4. The 1/2 is plenty, the belts will slip before it has issues. I have taken way deeper cuts than in should have in 1144 without issue (1/2 hp Grizzly motor).
 
I think you'd be wise to follow the advice above and swap or at least remove the motor. A lathe designed to run at 2000 max rpm might object, violently, to 4000. The next owner might not be as inquisitive about what's correct for the lathe and could wind up injuring himself or others. The frame type is usually listed on the motor tag and I've found used 1/2hp 56 frame motors regularly in the $15-20 range.
