weak MKVII motor

[RFGuy]

RF Guy, No, I haven't checked anything yet. I'm just asking the question if they ( if any motors windings) are burnt but not shorted/open, can it be repaired , if so , by who? This specific question is for me to learn more about electric motors in general, not nesessarily my SS motor.

If there is a problem internal to the motor, a repair shop can usually fix it. Typically they can troubleshoot, rewind, balance, etc. any electrical motor depending on the skill of the person in the shop. Sometimes it is cost prohibitive to fix a motor because replacements are cheaper than the repair cost...it just varies by geographic location and the particular motor. Sorry, I don't have any experience on motor repair costs for the Shopsmith motor(s).

In contrast, an Electrician can typically troubleshoot the wiring leading up to the motor, but nothing internal to it.

ok, thanks for the info guys.

I would spray 'electrical varnish' to prevent scorched enamel from flaking off and creating a short.

UPDATE:
I got an Avanti 10" 24T rip blade for my MKVII. It ripped a 2x4 with no noticeable slowdown of the blade. This was what I was hoping it would do. So I ripped 3 more 2x4s.
As an experiment , I mounted the rip blade on my powerkraft RAS, but the 2x4 made it bog down right away. Found out it's a 3.5 amp motor; so about 1/2HP according to my calculations. I was pretty disappointed with this cause my craftsman RAS has an 11 amp motor.

As an aside, I also ripped 4- 8foot 1x8s into 3/4" strips; so about 7 cuts per board. After about 1/2 hour cutting my thermocouple on my plastic speed cam follower read 134 degrees. Infrared check on the motor was about 125 degrees.
