For a given load:

Increase in supply voltage results in increase in armature drop. Increase in armature drop results in higher armature current. But we know that increase in armature current reduces speed. We also know that increase in supply voltage increases speed. What am I missing here?

Edit: An answer that I saw to a similar question said that the voltage difference between the supply voltage and the back emf is dropped across the armature resistance.

Now the above scenario would cause a flow of current through the armature, which produces the magnetic field required for rotation. So stronger the field, faster the rotation. But it is known that increase in armature current is a result of reduced speed.

For a given load:

Increase in supply voltage results in increase in armature drop. Increase in armature drop results in higher armature current. But we know that speed is inversely proportional to armature current. 

We also know that increase in supply voltage increases speed. What am I missing here?

I'd like to know how supply voltage affects the speed of a DC motor. I'd like a conceptual answer rather than one with mathematical equations. Any research I did only showed answers with mathematical equations.

If I increase the supply voltage, there is very little increase in armature current, and we know that speed is inversely proportional to armature current, so how does supply voltage directly affect speed of a DC motor?
