Quick Answer: The Engine Speed Control Apparatus is a scale-model engine driven by compressed air, used to show the problems of regulating the speed of rotating machines. A motorised valve regulates the speed while a d.c. generator on the output loads the engine.

About This Product
Students adjust the motorised valve to hold engine speed as the generator load changes, and see how non-linear behaviour makes simple control loops harder to tune.
Frequently Asked Questions
Is compressed air supplied with the Engine Speed Control Apparatus?
No. The scale-model engine runs on compressed air, which is not supplied.
