Topic tags/keywords: table saws motors wiring motors

I just recieved a Dayton 6K727, 1 HP, motor to power my vintage Craftsman table saw, Hay, it was free I can’t complain. Any way, it turns the wrong way, does anyone know WHERE I can find a diagram to rewire it to run the other way. All the info. I can find says it can be done ( Rotation—CW / CCW in all the Tech. Specs. )
If you can help me, Please email me at : loujcs@myfairpoint.net

Thanks Guys

How many wires are there coming out of the motor? What wires are tied together?

T8 and T4 are tied togeather
T3, T2, and T5 are tied togeather
T1 goes to the reset
P2 is Caped
P1 and T4 – T8 are not caped ( I would say these are what was tied to the power )

OH, I ment to tell you before :
The Diagram on the motor is / was under about 3 coats of paint, so it’s of absolutly no use to anyone.

This turned out to be interesting. I did a quick Google to see if I could find anything and although I didn’t find the wiring for the motor I found that it appears Dayton is owned by W. W. Grainger i.e Grainger. I didn’t know that.

Usually you can find the motor manufacturers web site and sometimes find the wiring but all leads on anything Dayton lead to www. grainger.com. And there it turns out this motor is discontinued and since it also appears from what I read Grainger is the only retailer for Dayton stuff so you might have to contact Grainger for the wiring diagram.

If you do I’d like to know how that works out, I’m curious to know what support there is for discontinued Dayton/Grainger motors from Grainger.

That sure don’t sound right though because you can find Dayton motors for sale all over. Unless those are used. Don’t quote me on this, it’s just what I read.

Ok maybe it is true found this:

http://www.grainger.com/Grainger/static/tf_m_daytonmotors.html

Dayton® Motors… Exclusively from Grainger.

So maybe you’re going to have to contact them. There is surprising very little information on this motor on the web.

One thing I did pick up on, it’s a 1725 RPM motor, is that the right speed for a table saw? The blades usually spin faster, is there a big pulley on the motor and a smaller one on the arbor to increase the speed? Just wondering.

Yes, the motor I took off was a 1750 RPM, so I will have to rework the pulleys, also this motor has a 5/8 shaft, the old one had a 1/2” shaft. I will have to get the book out, my formulas aint THAT good any more.
Another thing, I shouldset it up to run on 220v.

I think We Got It, I carefuly cleaned the diagram on the motor and the process of elimination, put a combination of wires togeather and it runs even in the right direction, BUT I’m not shure if its set for 110v or 220v, but it sounds good. I will get it tested tomorrow to find out if it is 110 or 220

The most typical arrangement for reversible single phase motors is to switch the connection of leads 5 & 8. If the leads aren’t numbered it is often the black and red.

dfarr – I think that is exactly what we ended up with.
Now, how can I figure out if it is set up for 110 or 220?
Thanks Everyone

You got me thinking with all the T8, P1, T5, etc. so it dawned on me this might be a NEMA or some standard marking and wiring. So I pulled out the schematic for the 1-1/2HP Leeson motor on my cyclone and compared it with your info, and yep I think it is.

So, for 110V CCW wiring:
L1 → P1
L2 → T2 T4 T5
JOIN → P2 T3 T8

For 110V CW wiring:
L1 → P1
L2 → T2 T4 T8
JOIN → P2 T3 T5

For 220V CCW wiring:
L1 → P1
L2 → T4 T5
JOIN → T2 T3 T8
INSULATE → P2

For 220V CW wiring:
L1 → P1
L2 → T4 T8
JOIN → T2 T3 T5
INSULATE → P2

Hey Lou, if it was a 1750 RPM motor and this one a 1725 RPM motor I wouldn’t bother redoing the pulleys just get the same size for the shaft. You may not even be able to pick one up in the incremental size you would need to do that. If they were 2:1 to get up to 3500 RPM you’re not going to notice 3450 RPM. And 1725/1750 RPM is due to the slip that is necessary to make the motor spin from the theoretical max of 1800 RPM (for that motor) and 1725/1750 RPM motors are pretty much used interchangeably.
