The motor of my Grizzly G0440 dust collector (2HP) is giving me trouble. It is drawing more amps than it should. If I have to replace it, I could install a larger motor. For example, I could turn my G0440 into a G0441 (3HP) by bolting on the larger motor Grizzly sells andgrizzly installing a new control box.
That got me thinking. Where can I find a non-Grizzly motor that has the same shaft/mounting holes? Are there standards?
