Nice explanation of the field excitation, Ken.
As for the automotive alternator's output voltage -- yes, it is regulated (usually by means of built-in power semiconductor circuits) to 14V.
And the power tool is designed for use with an (unregulated) 18V battery. So under heavy loading the alternator will actually deliver more voltage to the power tool motor terminals that the battery would, and therefore enable the tool motor to deliver more mechanical power to the application. The motor will not get up to the same free speed, but that may not be important.
Cirrusport, can you tell us more about your application?

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
