Commutator

The drawing at the left shows a cross-section of a structure which functions either as a commutator or as a low noise chopper.

Hollow tubular sectors 1a, 2a, 3a and 4a, fabricated of stainless steel and insulated one from another, are filled with liquid mercury. Rotatably secured within these sectors is a circular ring formed by segments 1, 2, 3 and 4. Each of segments 1 and 2 are also of stainless steel and segments 3 and 4 are of an insulating material.

Rotary motion is imparted to the enclosed ring by means of a magnetic clutch arrangement as shown at the upper right. One rotation of the ring provides two cycles of bipolar D. C. as indicated.

Digital information proportional to shaft rotation is provided by cascading several appropriately segmented commutators.
