I need to know the power of a flywheel

In summary, the individual is looking for information on the size of a flywheel needed to rotate from rest to 1450 rpm with a 1100 watt motor and to store at least 700 joules of energy. They mention a flywheel calculator, but are unsure if it provides the necessary information. They also clarify that power and energy are related but not interchangeable terms.
hi sir
i have 1100 watt motor and i want to rotat the fly wheel from rest to 1450 rpm.i want to know how big should be
the flywheel to rotate at the motor 1100 watt and to get extra energy 700 joule or more than if possiable
best regard
thnx

I'm not sure I understand what you are looking for, but doesn't that flywheel calculator tell you how big/heavy the flywheel needs to be to store 700J?

Also, just to be clear: power is energy per unit time. Flywheels store energy and how long it takes to dissipate that energy determines the power.

1. What is a flywheel?

A flywheel is a mechanical device that stores rotational energy. It consists of a heavy wheel or disc that rotates on an axle and is used to smooth out the fluctuations in rotational speed of a machine.

2. How is the power of a flywheel measured?

The power of a flywheel is typically measured in terms of its moment of inertia, which is the resistance of an object to changes in its rotation. It is usually measured in units of kilogram-meter squared (kg-m^2).

3. What factors affect the power of a flywheel?

The power of a flywheel is affected by its mass, size, and speed. A heavier and larger flywheel will have a greater moment of inertia and therefore more power. Additionally, the speed at which the flywheel rotates also plays a role in its power.

4. How does a flywheel store energy?

A flywheel stores energy through its rotational motion. As the flywheel spins, it builds up kinetic energy which can be released to power a machine or device. The heavier the flywheel, the more energy it can store.

5. What are some common uses for flywheels?

Flywheels are commonly used in machines and devices that require a steady and continuous power source, such as engines, generators, and electric motors. They are also used in transportation systems, such as trains and cars, to store energy and improve efficiency.
