Hello, hopefully the link will post... There are 2 motors available locally and I could use one for a lortone ls8 trim saw. In case the link doesn't post one is a 1/4 hp and other is 1/2 hp, both are 1725rpm. I am thinking the 1/4 hp one would be best for the 8" saw... Also, is there usually an indicator on the spec plate that says which way they spin? I have heard that you can often times reverse the direction by changing a wire location however I am not very electrically inclined and simply wiring it up may be pushing my skillset...anyway here goes trying to post the link! www.facebook.com/marketplace/item/936123350819031/?mibextid=dXMIcH |

The 1/2 doesn't show a base which would make it hard to mount. My Raytech 6 and 10" saws came from the factory with capacitor start 1/3 HP motors. The 1/4 in your photo looks like an older motor and will likely do the job you require. No, electric motors usually do not have direction of rotation on the spec tags, and yes, many motors can have direction reversed. It is easy to do, probably tutorials on youtube.

1/4 horse is OK, 1/3hp better for the saw, 1/2 hp is over kill but would work if you can mount it.

Thx y'all!! This site is such a great place for information. I will likely message the guy about the 1/4 hp motor, didn't even think about the base so thanks for bringing that up. Everyone has been very kind so far, I will do my best to comment on stuff if I think I have anything useful to say : )

For the sake of the conversation, it looks like the 1/2 HP motor does have a base, probably quite narrow as compared to the 1/4. There is a clamp around the vibration ring on the motor end, and likely the same on the other end, indicating there is something underneath, possibly only a pivot rod, but still easy to mount. Another thing I thought of: I've often seen motor reversing instructions on a label on the inside of the removable cover where the power cord goes in.

That 1/4 horse looks like it has windings as least as big as the 1/2. I bet that old 1/4 has the torque of a modern 1/3 and will power the 8" say just fine.

Hello again...
I was able to pick up both motors for 25$ total so I have both here with me. The 1/2 hp motor has a plug already wired and is surprisingly a bit lighter weight than the 1/4 hp. It also has a frame for mounting. Plugged it in and it spun ccw however right on the tag it said which 2 wires to switch (this case red and black) so me even with my limited wiring knowledge got that taken care of!
The 1/4 motor has wiring coming out of it but no plug (see photos). Did I mention it is heavier? The thing is a beast. The one thing it has going for it is it has a cap for oiling.
Now my question is this, it was mentioned that the 1/2 hp would be overkill for an 8" trim saw...besides that is there any good reason not to use it?
I could use the 1/4 hp motor on a lortone 6" arbor i have in storage...
Lmk, that's all for now; and thank you kindly!!
Josh

Great deal! The 1/2 hp is about $175-200 new.
I would agree that 1/4hp is adequate for 8 inches, but 1/3 or 1/2 would be fine. The 1/4 shown would be okay for something you don't walk away from, but those old heavy cast steel motors run hot and have been known to start fires, so never on a tumbler...
The 1/2 motor shown isn't ideal for wet locations, TEFC, Farm duty or wash down type motors are better for that. But it's the blower motor a lot of people use, a little care and maybe a spray shield that doesn't interfere with cooling. There should be oil holes for the sleeve bearings instead of cups, you can loosen the end clamps a little and turn the motor on it's mount until the holes face up.
