Hey Dawgs!
I've got a bit of good news to share as well as a couple of questions I think I know the right answers to, but if there is a better way to do it, then I'd love to hear about it.
Yesterday my new 3 Phase 2hp Motor/VFD set up came in! I went with a 2 hp, because I felt the deal as just too good to pass up!
Waa hoo! Now I've finally got some of the 20th century technology! That I've so seriously needed, I've been grinding with a single speed of 3650 rpm's! I hope learning at that speed may be in some way helpful for making my grinds a little cleaner, I hope!
I talked to my bro-in-law about helping me hook it up, (one of those better SAFE THAN SORRY DEALS!) HE'S A CERTIFIED ELECTRICIAN, HVAC rated too, MY Bro-in-Law is the best Bro-in law in the world!!!!!
I plan on hooking it up as a direct drive, he mentioned using a Lovejoy connector, it should enable me to connect the motor shaft to the drive shaft of the grinder. While that looks like a great way to do it and certainly a viable way to make that connection. The best I can tell, is that it should work, BUT! I'm not sure if that is the BEST WAY, (I'm simply saying, I DON'T KNOW!) There could be something I'm not aware of, that may work better, so if anyone knows of a better way or what would be considered the best way to make this connection.
Making my KMG into a direct drive, may not be the way it was intended to be used, i don't know. While I'm not sure if they were designed to be a direct drive.
I'm pretty sure they were NOT designed to NOT be capable of being a direct Drive!
Next, if my base plate isn't drilled and tapped for the motor, the holes in the back will have to be done with the right alignment in order to get the motor lined up properly, that will be the toughest part of this, if I have to drill and tap the Beaumont 1/2" base plate, I bought for the grinder, motor, and (I hope I can rig up) a place for my VFD.
Next, the place I got my motor/VFD from, (while it was a GREAT PRICE), their price for a NEMA 4 box was a lot too much, while I'm not sure how much they cost anywhere else, I felt like $400.00 for it was too expensive(THE PRICE FOR THIS BOX WAS NOT!), I felt like I could weld a box up for it, that would protect it, provided I can get a decent seal on it, my plan was to weld it up, not trying to get it to be air tight with the weld, but come back behind that with some sort of Silicon sealant, that will fill any gaps, now the front of it, that will be the main problem, being able to seal it and get to my controls. Now, I haven't really sat down and looked at any other boxes or any other solutions that others have come up with so they wouldn't have to purchase one, like I said I don't know how much they cost at other places, I don't have the dimensions of my VFD inside the house, but, I'm sure there has been some others that have come up with a different way to take care of their VFD's without buying a box, OR they found a place that sells them for a reasonable price! If anyone knows of that place, where I can buy one reasonably, please let me know, where and about how much, it would be I can get the measurements when needed. It would be much appreciated. BTW, I also had the idea to weld up some thermo- plastic, as another possibility, I want to explore every idea that won't cost too much, but the one that I do choose, will be the one that will be there. With BLADE so close, I don't want to spend any extra money anywhere that's not planned.
OK, Thanks guys, I appreciate any info y'all can give me, time for me to get back to the shop!
