1Q40.23 Centrifugal Governor

Mount the governor on a motor rotator and turn it on. The increased kinetic energy of the balls allow them to spin out and compress the spring.

This small model of a centrifugal governor consists of a spring coiled around a straight vertical shaft, fastened into a motor. Two cross-bars extend from the top of the shaft, each with a metal ball fixed at the end. The metal bars hang downward at a sharp angle. Secondary linkages stretch from roughly the middle of each cross-bar down to the bottom of the shaft, below the spring, where they attach to a sliding ring. These jointed cross-bars and ring are arranged so that when the balls rise toward the horizontal, the spring is compressed between the rising linkages and the fixed upper cross-bar pivot. The entire apparatus appears slightly blurry, as if the photo were taken when the motor was spinning the apparatus. In the foreground, a hand turns the speed dial on the motor.
