Electric Motors/Arboga E825 1Ph 220V Motor Wiring
Helping my brother with his recent purchase of mill-drill Arboga EM 825 (made in Germany- built for Canada in late 60 or 70's).
Machine was purchased with rotary switch removed. There is number of wires from motor that need to be connected to new 3 position high low rotary switch along with capacitor and start stop contactor.
Motor is integral part of machine and info on machine name plate is:
1 PH 60 HZ
n 3350 1680
There is two sets of speeds - 4 for high range and 4 for low range.Speed change
Number of leeds from motor are 7 plus ground.
Wires coming from motor color and numbers are:
Yellow 2 P2
Silver(Gray) 3 0
Red ( no number).
Also there is two wires from Capacitor 20 nF disconnected.
Gray Green 4.5
Gray Yellow 6.8
Gray Blue 3.8
Gray Red 12.5
Gray Brown 14.2
Gray Black 16.2
Green Yellow 13.5
Green Blue 8.3
Green Red 13.7
Green Black 17.5
Green Brown 9.0
Brown Blue 11.0
Brown Yellow 5.6
Brown Red 2.1
Brown Black 2.1
Blue Yellow 7.1
Blue Red 10.4
Blue Black 12.7
Yellow Red 4.1
Yellow Black 7.9
Red Black 4.8
I do not have wiring diagram for this mill-drill.
I am looking for information how to properly indentify wires and test motor.
Hope you can help guide me in the right direction. Thanks
This is one complex device, trying to ohm that out on a workbench would be hours and hours, if not days
Any chance at all of finding the original wiring diagram?
Is the two sets of speeds based off a mechanical selection? In other words is there a lower gear ration, then a higher gear ration then four speeds each?
This is a ton and the fast way is to find the original diagram, I can tell you the higher values are likely start circuit and the lower are run circuit, but a ladder diagram needs to be made from these values using the windings in the ladder, no small task,
It can be done, but it will take time, is there a decent motor shop near you, they should be able to put variable low voltage to the windings and create the circuits without using full voltage, maybe 40 or 50 volts, if the ladder diagram starts reversing or some other issue,
That link is a parts breakout, not any help with the motor but might be a help if you don't have it for other issues,
above link list a distributor for the parts, may have a manual for the wiring
Link above HAS THE ELECTRICAL DIAGRAMS price $35.00 if it has the motor connections and should it will be the best $35.00 spent to figure this out,
