I have a General Int'l 10" table saw, model 50-185, about 5 years old. In the last few days I have noticed a loss of power. The first time, I had done a rip cut with the blade tilted at an angle. It made the cut okay, but when I started the saw up to do the next cut, the motor sounded different, the blade started out slow, gradually picked up speed, but not to normal, and the motor slowed significantly with any load, even slowly feeding the wood (soft wood 1X board). I took off the belt guard and noticed that the arbor pulley was loose, and it looked like it had rubbed against the inside of the belt guard. I tightened the set screw, and put the saw blade back to veetical. I let the saw "cool off" for a couple hours, came back and it seen to start up fine. The next day, I made a couple rip cuts, soft wood, then oak, and after three cuts, the saw did the same thing, slowing down, stopping under any kind of load. That's where I'm at. Burned out motor?

Sounds like the run capacitor has given up. Or, maybe the worst is it overheated and burned the motor winding. You'll probably have to take it apart. If there is a smoked capacitor, that's probably the one you should replace. If the winding is scorched, might as well get a new motor. If both are the case, then replace the capacitor before you give up on the winding.

SOURCE: I'm feeding 8/4 alder through the powermatic strait line saw

Sounds like the power feeder is not holding it secure at the end of the pass. Is the outfeed table running level to the saw table?
Just a wild guess, I'm afraid. I haven't used one myself.
The only time I've seen blades wobble like that was when they were light plates, undersized for heavy duty ripping operations. It's truly frightening to watch them overheat and turn to butter like that. I'd recommend getting a heavier plated saw blade if there's any question about yours.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

Maybe it's under-wired? When you start it up, if the lights dim, and the saw takes 2 or 3 seconds to come up to speed, then your wire is definitely too small and/or too long. 14 gage wire is almost always too light, although a very short 14 gage extension cord plugged into a circuit wired with 12 gage is OK. The cord on the saw itself is probably 14 gage.

SOURCE: I inherited an older Delta 10 inch table saw.

Two easy possibilities are that the blade is dull or that the wire is too small. The wire is likely to be a problem if you are using an extension cord. You could move the saw near to an outlet that you know to be wired with 12 gage wire (not 14). Or you could buy as short as possible 12 gage extension cord. If being underwired is the problem, you will notice that the motor comes up to speed much faster when wired adequately. You might also buy a cheap new blade to rule out the dull blade problem. If neither of these fixes the problem, then the motor has become "weak" because it has overheated just enough to cause some minor shorts between the windings. (If the shorts are major it won't turn at all and will trip a breaker.) In this case the motor can be rewound, but it will probably be cheaper and easier to just replace the motor.
Good luck, Al K

The problem you have is a faulty field coil, the Bosch saws unfortunatly have a bit of an issue with this. The coil can be replaced separatly so you won't have to replace the whole motor. Bosch has a 1 yr warranty on thier table saw so this is a warranty replacment provided the saw was purchased within the year. If not the coil replacment is still cheaper than buying a whole new saw, but should really be done by a service center because of the level of difficulty of the repair.
