One thing you will want is a TEFC, totally enclosed fan cooled, motor. This will keep the crap that floats around a knife shop from getting into the windings.
Compressor duty motors usually have the addition of oil capacitors, or running capacitors. This allows them to have more torque than a regular farm duty motor, and for many compressors, high-torque is a priority. They can run this way, because they usually don't do it for more than a few minutes at a time.
IMO, a farm duty motor will do nicely for whatever application you have in mind. Your list of requirements seems to be just right. Remember, farm duty means that these motors will be turning feed augers, conveyors, and other farm equipment, and that's pretty tough work. Much more difficult than powering a grinder.
