Rotating Force

- The "brushes" of a large elevator motor make contact against the "commutator" which rotates on the shaft. The commutator is essentially a switch which reverses the electrical current direction of the motor's armature creating a steady rotating force. This motor was very large, about waist high from the floor. Canon G1X, 1/13 sec @ f/2.8, ISO 1600.
