What is a flywheel in simple terms?
A flywheel is a heavy wheel that makes an engine move smoothly by storing kinetic energy and keeping the engine at a constant speed throughout its cycle. Without a flywheel, car engines would be very jerky. The flywheel stores energy and makes the pistons move at a constant speed.
Is a flywheel part of a clutch?
The flywheel is the interface between the clutch system and the engine. When your foot is off the clutch pedal, the clutch disc presses against the flywheel, locking the engine to the transmission. When you apply pressure to the clutch pedal the flywheel is released, disengaging the transmission from the engine.
Does the flywheel always spin?
So, you might think the flywheel spins all the time. That's not true. The flywheel does not spin when in neutral. This is because the input shaft that connects to the clutch plate; then to the pressure plate which connects to the flywheel is designed to spin freely when the vehicle is in neutral.

Traditional flywheels used in the Industrial Revolution were very large, and very heavy. The practicality of putting this type of wheel on a motorcycle would certainly lead to some difficulty riding! So, flywheels have been adapted for specific purposes, including motorcycles. These flywheels offer exactly the same functionality but are adapted to fit within the mechanics of a bike.
Why do motorcycles have clutches?from venhill.co.uk
Clutches and gears on a motorcycle help improve the performance of the engine. They help give the rider more control over the speed, even if the engine is going at the same speed. However, neither the clutch nor gears can help solve the problem of wasted energy, which is why the flywheel is another key element of a motorcycle.
Why is the flywheel important?
Flywheel effect is also important in dirt-track racing, where its ability to smooth out engine torque can improve hook-up and acceleration on slippery tracks. I’m told that turning the rear wheel into a big flywheel is something tried so often in US flat-track that AMA Pro Racing has now set a maximum wheel weight.
What is the flywheel effect?
Normally when we think of flywheel effect, we are thinking of how the weight of a crankshaft can affect idle or acceleration. Typically, single-cylinder engines have had quite massive flywheels for the purpose of storing enough kinetic energy at idle rpm to push the piston through its next compression stroke, thereby keeping the engine running.
How many times does a flywheel have the same effect?
The basic physics of flywheels says that the flywheel effect is proportional to the square of the radius at which the mass is located. This means that one ounce of flywheel material located at the rim has four times the flywheel effect of that same one ounce, located halfway between rim and center. In a flywheel pair for a 1916 Indian 'Powerplus' ...
What is a flywheel?
Flybird is a type of electrochemical hybrid commonly found and makes use of flywheel instead of battery for storing regenerative braking energy. The stored energy is utilized for giving or maintaining mobility of vehicle.
Why do we use flywheels?
Use of flywheels in mechanical devices helps to smooth the movements that are prone to sudden rapid outbursts. In auto, flywheels are used to keep the power of engine at even speed. When a flywheel is connected to an electric motor it stores electrical energy in the form of kinetic energy and thus performs the function of a battery. Flywheel batteries last longer than the chemical batteries and hence are nowadays being used more often.
How does a flywheel store energy?
The energy storage of flywheel is like a mechanical battery which stores kinetic energy in rotating mass form and when required this energy is then converted into electrical energy by using integrated electric generator of flywheel. The energy thus created is enough to provide DC energy for UPS in an emergency until a stand-by diesel generator is attached. When its utility is complete or another power supplier becomes available, it is recharged by connecting to the UPA of DC bus.
What is the function of a flywheel?
More precisely, a flywheel's stored energy will donate a surge in power output upon a drop in power input and will conversely absorb any excess power input (system-generated power) in the form of rotational energy. Common uses of a flywheel include: Smoothing the power output of an energy source.
What is a flywheel made of?
High energy density flywheels can be made of carbon fiber composites and employ magnetic bearings, enabling them to revolve at speeds up to 60,000 RPM (1 kHz). Carbon-composite flywheel batteries have recently been manufactured and are proving to be viable in real-world tests on mainstream cars.
How do flywheels work?
Flywheels are often used to provide continuous power output in systems where the energy source is not continuous. For example, a flywheel is used to smooth fast angular velocity fluctuations of the crankshaft in a reciprocating engine. In this case, a crankshaft flywheel stores energy when torque is exerted on it by a firing piston, and returns it to the piston to compress a fresh charge of air and fuel. Another example is the friction motor which powers devices such as toy cars. In unstressed and inexpensive cases, to save on cost, the bulk of the mass of the flywheel is toward the rim of the wheel. Pushing the mass away from the axis of rotation heightens rotational inertia for a given total mass.
What is the moment of inertia of a flywheel?
is the moment of inertia of the flywheel about its axis of symmetry. The moment of inertia is a measure of resistance to torque applied on a spinning object (i.e. the higher the moment of inertia, the slower it will accelerate when a given torque is applied). The moment of inertia for a solid cylinder is.
How is the efficiency of a flywheel determined?
The efficiency of a flywheel is determined by the maximum amount of energy it can store per unit weight. As the flywheel's rotational speed or angular velocity is increased, the stored energy increases; however, the stresses also increase. If the hoop stress surpass the tensile strength of the material, the flywheel will break apart. Thus, the tensile strength limits the amount of energy that a flywheel can store.
