Well, I think I'm about ready to purchase a spindle motor for the mill in progress, however, I'm about as dumb as a box of rocks when it comes to choosing a motor. I'm thinking a VFD with a good 3 phase motor would be great, but I really don't know enough to make an educated decision. I've seen that I can get a new 3hp Baldor or Leeson motor for about +/- $200 delivered. I've dug up some specs on some motors, but I really don't know what I'm looking at.http://baldor.com/products/detail.asp?1=1&catalog=VM3561&product=AC+Motors&family=General+Purpose|vw_ACMotors_GeneralPurpose&winding=35WGY334&rating=40CMB-CONThttps://www.surpluscenter.com/item.asp?item=10-2526&catname=electric
2 or 4 pole? Pro's and con's? I would like to have more power at slower speeds, rather than higher, so I guess a 4 pole is more desirable?
What about VFD options to look for? Needed inputs/outputs for features that might be useful, relays, braking features, fieldbus options, etc.... I have a small bit of experience with the Danfoss drives, and I know they are quality drives, plus and I have a local supplier, so I'm kinda leaning toward those.http://www.danfoss.com/BusinessAreas/DrivesSolutions/Products/Frequency+Converters.htm
I know I'm asking allot, but any help at all is appreciated. Thanks!
