Hi all,
Riddle me this. I recently found a SawStop PCS 1.75 HP used for a nice price. I have 220 in my shop and confirmed that I can upgrade to 3 HP, figuring I could use the 1.75 HP motor in my 2 HP Shop Fox dust collector. The dust collector motor has been making bearing noise when it's cold out for a while and I figure its days are numbered....and I could upgrade, fix the DC issue and still be way ahead cash-wise.
Here's the quandary: I checked the plates on both motors. The "2 HP" Shop Fox says it is 12 A at 220 = 6 A / HP. The 1.75 SS motor says it is 7A at 220 = 4 A / HP. Does this mean the SS motor is really 33% more efficient?
Best,
Chris
