I am putting a 5hp baldor ZDM3665T motor on to my BOSS cnc mill retrofit. The main idea here is to get the electronic speed range for the 2hp rating of the spindle. I may start using more power IF I monitor the bearings in the head and aren't getting to warm. You can see from calculations that this motor gives 2hp over the same speed range as the OEM variable speed drive does. I want to use a poly v belt and I cannot seem to find any literature on the load calculations for it! For standard v belt this is available no problem. Can anyone help?
