A centrifugal clutch shown in a patent application, 1898. Centrifugal clutches were used in railway locomotives before 1858, [1] and referred to (in relation to electric motors) in a patent of 1899. [2] A patent was issued in the United States for an automotive centrifugal clutch (on an electric vehicle) in 1898. [3]
The centrifugal supercharger draws its power from the movement of the drive where it is attached. At this point, the supercharger powers an impeller – or small rotating wheel. The impeller draws air into a small compressor housing (volute) and centrifugal force sends the air into the diffuser.
A two-shoe centrifugal clutch. The motor spins the input shaft that makes the shoes go around, and the outer drum (removed) turns the output power shaft. Another example of a rotating device in which a reactive centrifugal force can be identified used to describe the system behavior is the centrifugal clutch. A centrifugal clutch is used in ...

A centrifugal clutch is used in small engine-powered devices such as chain saws, go-karts and model helicopters. It allows the engine to start and idle without driving the device but automatically and smoothly engages the drive as the engine speed rises.
Based upon the size of the clutch or brake, the speed and the inertia, wear rates will differ. For example, a machine that was running at 500 rpm with a clutch and is now sped up to 1000 rpm would have its wear rate significantly increased because the amount of energy required to start the same amount of inertia is a lot higher at the higher speed.
Centrifugal switches were also used in early electric fans, particularly those made in the 1900s and early 1910s. [citation needed] In aircraft, a centrifugal switch is used to control the starting and ignition circuits, the governed speed indication circuit and the overspeed protection circuit of the auxiliary power unit. This switch is ...
A small engine is the general term for a wide range of small-displacement, low-powered internal combustion engines used to power lawn mowers, generators, concrete mixers and many other machines that require independent power sources. [1]
