What happens if you mount a compressor motor on a table saw?
I have a salvaged 2 hp compressor motor from an old compressor. The motor
is not as old as the compressor was. It is a Granger replacement..
You get high pressure sawdust blowing all over the place.
What is important is power, frame size (that determines shaft size),
voltage, rpm and rotation. It they are all the same or can be made the
same, it is compatible. Motors are usually made to certain specifications,
not a single use (although they do exist)
I have a "compressor motor" that turns the wrong way and is not reversible.
If your motor turns, or can be made to turn, the right way, go for it. I
expect most Grainger motors are reversible.
Most TS motors are 3600 RPM, I think, and the compressor motor is likely
1800, so you'll need a pulley with twice the diameter of the original.
"As I understand it" a compressor motor is not sealed adequately to deal
with the dust the TS will produce. As long as it is the right size, speed,
etc. it will work; but it might not work long.
If you have no other use for the motor you can see how long it lasts.
Compressor motors are often "open drip-proof" or ODP. Better motors for
shop use are "totally enclosed fan-cooled", or TEFC.
While TEFC is nice, its not strictly necessary. For a while I owned a
decades-old Rockwell table saw with an ODP motor. You just need to blow
the dust out periodically.

My Delta Contractor saw also has the original ODP motor. The saw was
several years old when I bought it, about 8 years ago.
When the game is over, the pawn and the king are returned to the same box.

As did almost all the Delta/Rockwell contractor saws. However, keep
in mind that those motors were purchased with an engineered and tested
dustproof centrifigal switch (the switch that shifts from start to run
circuits and back). Without it, an ODP will constantly be a problem
in a woodworking application. And not all ODP motors have them.
