Hi All,
Ok last year I ordered a VFd only to find out that I had a 1 phase 1.5 HP grinder, I could not quite swing a new motor at the time so I returned it.
Well here I am again, looking to get the most out of the ceramics belts I buy.
I think I have purchased the correct set up. I have read and read and read old threads and I think this will make a good team. But still not positive! LOL. I am just asking here to make sure im not ordering the wrong stuff again.
I am going from a step pulley mounted that is attached with a large v belt to motor under the bench/ almost on the floor. I think my horrible belt efficiency is related to this and a huge loss of torque under pressure. So with this set up I will now have a direct drive VFD and still be able to plug into 110V. I got the lower RPM motor to have increased torque.
Another issue I may have is my drive wheel. I made it myself quite awhile ago. Its a 5" diameter solid aluminum 4" wide. . Would extra mass in the drive wheel have any negative consequence? Should I machine out some weight to this?
So this is what I have ordered.
1.5HP 1725RPM 56 3PH 208-230/460V TEFC LEESON ELECTRIC MOTOR #116759
