Dewalt Dw871 Replacement Motor

I have searched the net and called Dewalt and cannot locate a replacement motor for my dewalt dw871 metal chop saw, The motor throws sparks when in use and I have replaced the brushes but no change.  Does anyone know of a replacement motor/cross reference?  Thanks in Advance

Just buy a new saw. It’s not much more than what a new motor would likely cost you.

I would just. get a new one. Sometimes it is more expensive to repair than to replace.
