Hey guys, looking to get a motor for polishing estate pipes... I have a table mounted one for a grinder and 3500rpm is a tad fast.
See a (semi) local guy selling them for $25 each, has 5 of them... the last 3 look to be the correct speed, but, the "frame" I have no idea what that is. That, and 3/4hp vs 1/3hp... same rpm not sure which would better to get.
- 1 HP, 550 V, 1.3 A, 3,450/2,850 RPM 2-speed, Frame 56
- 3/4 HP, 550 V, 0.94 A, 3,450 RPM, TEFC, Frame 56/T6
- 3/4 HP, 550 V, 0.84 A, 1,725 RPM, Frame 171
- 1/3 HP, 550 V, 0.55 A, 1,725 RPM, Frame H56
- 1/3 HP, 550 V, 0.55 A, 1,725 RPM, Frame H56
I also saw a post in passing once, someone saying they needed to reverse the rotation to counter clockwise... not sure if that's just their preference based on how they mounted it to the table? or if something to do with preventing the bolt holding the buffing pad on from unwinding. Wish I could find that article again, had a link to a pipe tool store that sold adapters for the motor for attaching pads.
Figured I'd post here, see if anyone has any advice/help... Thanks
