Quick Answer: The Watt’s Regulator, also called a Watt governor, demonstrates how a centrifugal governor controls the speed of a rotating machine: as the speed rises, the governor balls swing outward and lift the sleeve.

About This Product
Starting slowly and then raising the speed, students watch the governor balls swing outward and the sleeve climb the spindle; slowing down reverses the movement. The observations explain how engines and rotating machinery regulate their speed automatically using centrifugal force. Enquiries from Sudan, Serbia, Seychelles, Dominican Republic and Bahamas for the Watt’s regulator receive an export quotation.
Frequently Asked Questions
What happens to the sleeve of the Watt’s Regulator as the speed increases?
The governor balls move outward under centrifugal force and the sleeve moves up; when the speed falls, the balls move in and the sleeve moves down.
