Table saw spinning the wrong direction.
Hello everyone first time poster here.
i recently acquired a table saw from my uncle. It is the rigid TS-3650. He bought that years ago. Table saw still works great and after a little cleaning and rust removal it looks pretty new. So I’m trying to fix the rotation of the motor. Now I have scoured the web to figure out how to rewire the motor. The motor is a delta 62-044. My question is can this motor be rewired to change the rotation and if so how can I do that?
i couldn’t find a spec book. I could buy another motor but this one works great. And the table saw is in great condition
I will provide pics of the motor.
i do appreciate you time looking at this. I’m not the most knowledgeable when it comes to electric but I’m fairly confident I can fix this. Just need someone to point me in the right direction.
This might be helpful as well if the wiring is correct per the diagram, which it appears to be best I can see from the pictures. https://sawmillcreek.org/showthread.php?128972-Table-Saw-runs-in-reverse
I take it that is not the original motor. Your motor appears to have come off a Delta 62-044 table saw which was a right tilt model and I'm quessing the Rigid tilts the blade to the left. This means the motor is install on the opposite side as intended. AC induction motors are not as easy to reverse as DC motors, which simply require reversing the polarity of the wires. The wires need to be reversed at the starter winding to reverse the magnetic field. Since this particular motor doesn't specifically state it is reversible and provide instructions for doing that, it may require disassembly of the motor to access the starter windings, not something I would advise for anyone needing to ask this question.
I believe this motor is operating as intended but it was not original for this saw. The post you linked to refererred to an inexplicable change in rotation but I don't think it applies here. Barring find a specific wiring diagram for this motor that shows the schematic for CCW rotation(the one on the motor is just for operation voltage) or more insight from a more knowledgeable individual I will advise not to try, since many AC induction motors are not intended to be reversed and require accessing the internal starter windings.
I was wondering if it had been mounted backwards as well. On the motor plate it states the motor turns CW, so if in fact the motor is doing that, then it's possibly mounted backwards. More info will be enlightening.
Okay after asking my uncle about it. His workers did replace the motor. They just happen to chose the wrong one.
It's not necessarily mounted backwards but simply designed to be on a right tilting saw, which mounts the motor on the right and requires CW rotation. If the Rigid is left tilting the motor is on the left and requires CCW rotation.
If it does what it's supposed to, let it be.
Mikaol the problem is it isn't doing what it's supposed to. You can't safely use a tablesaw that is rotating in the opposite direction it would tend to lift the wood off the table and try to fling it.
Maybe it's a Japanese table saw. Cuts on the pull, not the push.
Looks I’ll just get a new one.
All these explanations and no one suggested taking it to an electrical motor rewind shop and asking if it can be reversed (through the starter windings) and the cost to do so. --I'd bet a lot cheaper than a replacement.
I can speak from experience, at least in Northern Virginia that motors under 3 hp. are generally cheaper to replace than repair, that may not be the case where you live but I would try to find a good second hand motor maybe trade the Delta, it is a good motor, for one.
Looking at the picture of the wiring, it appears that we are looking downward and you can see the left rear leg and the floor. This is confirmed by a picture of the back side of this model I found on the net. The motor drive pully is on the left side (as you are standing on the infeed side of the table). That is correct for a CW rotating motor on a left tilt saw. So, is it possible for the CW motor to be actually running CCW?
Sorry. But, I must ask because no one else has, is your blade on backwards?
Bilyo. If you look at a picture of a TS-3650 you will notice it is a left tilting arbor saw with the motor mounted on the left side as you stand at the front of the saw. The Delta 62-044 contractor saw that that motor came from is a right tilt arbor saw, as most Deltas of that era were, and had the motor mounted on the right side of the blade. Right tilt saws take motors that rotate CW while left tilt arbor saws need motors that rotate CCW it simply is not made for that saw.
While I have no experience with respect to the cost of rewinding single phase small horsepower motors, here in Canada one can save quite a bit of money having alternators and starting motors rewound. I have no reason to believe that it wouldn't be the same for this motor.

With respect, you are, at the same time, correct and wrong. The direction of rotation for a left tilt saw is CW if one is looking at the motor from the drive pulley end. However, most of the comments above (including mine) overlooked the "OPE" designation on the motor label. It means "Opposite Pulley End". So, "CW OPE" means that the motor rotates CW when looking at the end opposite of the drive pulley. Which means that when properly mounted on this saw (TS-3650) it is, in fact, rotating in the wrong direction. Of course, the OP already knows this and it does not answer his question ;>)
