Mystery Wiring, Need Help.


Here are a bunch of pictures. The last one being how my shops electrical guy wired it and it runs. If there is another way I'm open to hear from anyone. The white thing on the back says 30Ω 10W. Now I also need to know how to control the speed and preserve as much torque as possible...?

And how did he hook it up ? In yet a third manner, of the very-very simplest mode of taking the series winding and hooking the armature windings in series with it.
Did the motor run direction come out OK ? . . .if it is being relevant ?

This is just about how 90% of these AC/DC Universal motors get wired up.

It would truly involve taking some dyno, tach and strobe testing to truly specifically evaluate the startup torque / load / speed control aspects.
For the testing out and evaluating developed specs of the motor in all of its 3 possible utilization modes.

If this unit really gets USED, there was also the 2MO57 with its ball bearings.
Any chance that its ap is for an industrial duty sewing machine ?

(Seems like I have had dealings with WW Grainger and their Dayton brand since 1958.)

They are offering their 5JJ60 for its 20---100% speed control capability..

Thanks for the info. I'm hoping to use it to power a small lathe.
I do however realize that I am wasting all of your time, as nothing you all are saying makes a bit of sense to me. I am also without any diagnostic equipment to use even if I understood what I was supposed to do. I got one of them hooked up and running. I'm pretty sure it needs bearings.. if this little thing can even be rebuilt? I guess being cheap just got expensive. I'll most likely just buy a new motor. Thank you all for your support in my failure.
 
Not a very good choice for a lathe spindle, and at 1/15hp would only be useful on a very small table top unit.
You could gear it down to increase torque and obtain a realistic RPM.
The other way on AC is a simple Triac controller but torque will suffer as rpm goes down.
The reason for the resulting high rpm is that a Universal motor, being a series field motor, essentially operates in a run-away condition due to field weakning and is only rpm limited by friction and windage.
Odd, the 30ohm resistor appears to go from C1 to C2?
You may be better off to look for a DC motor, ex treadmill etc.
