low or medium inertia for router?
Hi, I'm looking for replacement x-axis motors for a CNC router with a fairly heavy steel gantry in the 500 lb. range. I'd like rapids of at least 1200 IPM. I'm thinking I'll need something in the 1.3 KW range.
Should I be looking only at low inertia motors? The literature describes the medium inertia motors as being suited to "heavier loads". Do the quick direction reversals required in normal router operation dictate a low inertia motor?
Does anybody have recommendations for what the best bang for the buck is in the used market?
