After running a few 3/8" dado cuts, the motor shut off and I had just a wee bit of smoke coming out of my jet 3hp motor, and it was quite warm to the touch. I’ve had this saw for 15 years or so, but it has had very little use, so it’s nearly brand new… 🙁
Removed fan cover, fan blade and centrifugal switches. Both parts of switch look like new. No dust underneath/inside fan and inner cover. Having trouble getting end off motor. Mine has 3 external threaded bolts that run the entire length of the motor with a phillips head end on one end and 2 small nuts. Removed the six double nuts holding it onto threaded rods. It spins but won’t come off…just curious how you removed the end cover of this motor and also what you would check if the motor starts perfectly and then runs, but after about 30 seconds of smooth running, it smokes just a tiny bit and then shuts off the motor… Would love to be able to repair rather than replace if possible! Thanks!
having trouble taking off the fan and the housing, did you have to use a puller to get it off?
I’m not sure you will see this post. My neighbours shop is throwing out an old Rockwell TS 34-457. It has a Single Phase Rockwell 3HP 83-621 motor. He described the issue as follows. Table saw powers up fine and spins but once cutting plywood the motor trips (not the panel) and then comes back on. He thinks it’s the windings. I’m completely green in electrics. He said he started to trouble shoot but lost interest when he came across a new saw. I’ve searched google and can’t seem to find this issue. It’s more about the start-up capacitor. Is there a run capacitor ?. The motor seems to run just fine when i started it and left it idle. Any quick checks I can try to save this from the Recycle Yard ? Many Thanks, Bruce
Looking to replace the bearings on my jet motor. From the looks of it, you have the saw I have. By any chance, do you remember the sizes on the two bearings in the motor?
Where can I find parts for these motors
Hey how’s it going, how did you get to the motor?. My panel seems welded on. Driving me crazy
