I forgot to mention another interesting thing that I noticed on this particular motor. The tag says that the insulation is rated "Class H". The NEMA standard says that a Class H insulation rating means that the internal operating temperture of the motor should not exceed 180 degrees C which is 356 degrees F! That's hot!! I would certainly hope that it would never approach that but nice to know that it is rated that high anyway. I do have a motor temp probe for my dash readout so I'll be monitoring that as I test.
