Centrifugal Governor Apparatus Model MT 041

* Visualization of the effect of centrifugal force1
* How various centrifugal systems work1
* Determination of characteristic curves and setting curves of different centrifugal governors

Item Description

Centrifugal governors use the properties of centrifugal force to regulate the speed of a machine. Due to  centrifugal force, a rotating flyweight mass has the tendency to move away from the axis of rotation and is prevented by counteracting mechanisms. These mechanisms are differentiated into those governors that use weights and those that use springs. Corresponding kinematics cause a deflection proportional to the rotational speed to occur on the governor. Via an actuator, this affects the energy supplied to the machine, thereby regulating the machine’s speed.
Sci-tech Centrifugal Governor Apparatus Model MT 041 experimental unit presents centrifugal systems that demonstrate the different principles of operation of both weight and spring-based governors.
