What is a Flywheel in a Car?

A car’s flywheel is a circular wheel attached to the engine’s crankshaft that stores the engine’s mechanical energy during the power stroke and transfers this stored energy to the preliminary strokes (i.e. intake, compression) during engine operation. , and exhaust stroke). Made of steel or cast iron. It is mainly used in motors and manufacturing machinery such as rolling mills, presses, shears, and presses.

Types of Flywheels

Following are the types of Flywheels:

Rimmed Flywheel

Rim-type flywheels explode at much lower RPM than full-face wheels of the same weight and diameter. For minimal weight and high energy storage capacity, the flywheel is formed from high-strength steel and manufactured as a conical disk with a thick center.

Solid Disc Flywheel

A solid disc flywheel is a type of flywheel. Used for cast iron single flywheel threshing machines. A full disc flywheel has a flywheel hub and a disc attached.

Various parameters are used as inputs in the full-disc flywheel design calculations. This includes dimensions for flywheels with solid discs. In addition, the resulting function value is calculated.

High-Velocity Flywheel

For these types of flywheels, the speed of the high-speed flywheel is from 30,000 rpm to 80,000 rpm. This is also adjustable up to 1,00,000 rpm.

High-velocity flywheels have magnetic suspension bearings & require little maintenance. These are lighter weight compared to low-speed flywheels depending on their size/capacity. More expensive than low-speed flywheels.

Low-Velocity Flywheel

For these types of flywheels, the low-speed flywheel has a speed of 10,000 rpm. They are heavier and bulkier than high-speed flywheels.

It requires regular maintenance and does not use magnetic levitation bearings. Their installation requires a special concrete structure to support the weight. Cheaper than a high-speed flywheel.

Concept of Free energy

How does a free energy generator work?

Concept of Free Energy

Most new technologies have been discovered over time and have brought about profound changes in the perception of electrical energy. However, at the same time, there is also a misunderstanding about “FREE ENERGY”.

The energy that has no cost is called free energy. It converts the mechanical energy that drives windmills or the solar energy of solar cells into direct currents. Other energies available are wind, hydro, and tellurium power. A Free Energy Generator is a method of generating free energy. Unlimited electricity is available everywhere, powering devices around the world without gas, coal, or oil. However, there is no free energy in reality. Electrical energy from solar panels, wind, geothermal, and hydropower will only become free once the methods of generating this electrical energy are operational by providing a capital cost.

These unconventional methods of generating electricity mean that you don’t have to pay for generation, so the energy is ultimately just free. From this, we can conclude that we can obtain sufficient amounts of energy from the local environment to meet our primary needs. This basic fact is denied on every occasion by conventional scientists who have decided not to accept it. The main reason for refusal to accept this fact appears to be perhaps financial gain. The correct scientific method is to improve scientific theories through observed facts and new discoveries, but the true scientific method is currently not followed.

Free Energy Generator with Flywheel

A free energy generator uses this strong magnetic field to rotate the shaft of a motor. It works on the principle of neodymium magnets, whereas ordinary generators work on the principle of electromagnetic induction. Examples of free energy generators are flywheels and magnets.

The basic model of a free energy generator with a flywheel basically consists of the following components:

A Flywheel

A free energy generator where energy production occurs entirely from gravitational energy. We use a flywheel of considerable mass (kg) which is used for gravitational energy for more power.

A Generator

The generator is used to produce electricity.

A Motor

The engine is used to drive a series of belts and pulleys that form a gear train that more than doubles the speed on the generator shaft.

Connecting Shaft

Here we use two waves in the layout of the system. The shaft design should be calculated to find the proper shaft diameter that will easily withstand the load and provide maximum energy transfer with minimum losses.


Bearing selection is also an important criterion for the smooth long-term functioning of the system.


Pulleys are used for belt drives.

Belt Drive

Belt drives have been found to be suitable for power transmission through pulleys. In the first stage, pulleys were selected according to standard specifications. Each pulley has a different diameter and speed. Belt and wire (rope) drive are used for power transmission. This project uses a total of 6 pulleys, so 3 different belt drives are required.

Working Principle

A 0.5 hp line motor is used to drive a series of belts and pulleys that form a gear train that more than doubles the speed on the generator shaft. What’s intriguing about this system is that more power can be drawn from the output generator than the input drive being drawn to the engine. Tseung’s theory of gravity explains that when a pulse of energy is applied to the flywheel, extra energy equal to 2mgr is injected into the flywheel at the moment of the pulse. where ‘m’ is the mass of the flywheel, ‘g’ refers to the gravitational constant, and “r” refers to the radius of the flywheel.

The distance from the axle to the point on which the mass of the wheel acts. If all of the flywheel’s mass is on the rim of the wheel, “r” would be the radius of the wheel itself. It means if the drive is restless, then there will not be a gain in energy. However, extra energy is drawn from the gravitational field in case the drive is not smooth. This rise in energy tends to the rise in flywheel diameter.


Based on the above studies on free energy generators using flywheels, the following conclusions are obtained. It is clear that cast iron flywheels are subject to greater stresses and deformations. Using S Glass Epoxy in the flywheel allows energy to be stored with less mass. Environmental concerns, combined with the demand for increased operational reliability, are likely to drive demand for new distributed generation systems that integrate grid-coupled and small energy storage devices. Flywheels are an excellent solution and enable market expansion. There is 18% additional power.

Frequently Asked Questions (FAQs)

What is the flywheel connected to?

A flywheel is a heavy disk-like structure that is connected to the engine’s output shaft by a crankshaft bolt.

What is the difference between a battery and a flywheel?

Well, you can compare it with the mechanics of a mechanical battery. Batteries store energy in chemical form, whereas flywheels store power in the form of motion or kinetic energy to be exact. A flywheel can store more energy the faster it spins or has a higher moment of inertia.

What determines the size of the flywheel in an engine?

Flywheel size depends on the number of cylinders and engine design. The power flow out of the engine’s cylinders is not smooth. However, in a multi-cylinder engine, the power impulses overlap to give a fairly smooth power flow.
