Background

This generator was made by ARCo p/n: 1090600 to demonstrate how AC or DC electrical generation is controlled by the commutator.

Description

The hand cranked generator uses a circular rubber belt to speed up the generator.  The generator consists of a couple of iron pole pieces topped with a permanent magnet.  There are two commutator systems.  In Fig 1 you can see the two AC brushes that make contact over 360 degrees of generator shaft rotation.  In Fig 2 you can see the split disk commutator that reverses the polarity every 180 degrees.  Fig 3 shows the wiring that's under the bottom cover plate.  The 3-way switch is AC-Off-DC and connects the appropriate commutator output to a lamp.
