What is Flywheel Torque?
Flywheel torque is the rotational force exerted by a flywheel in motion. It is a measure of the effort required to change the flywheel’s rotational velocity, which is influenced by factors such as mass, radius, and angular acceleration. Flywheels store rotational energy and help stabilize mechanical systems by providing inertia, especially in situations where the energy input or output fluctuates. Torque is a key parameter in understanding the flywheel’s capacity to store and deliver energy efficiently.
Das formula for calculating flywheel torque ist:
Flywheel Torque = (Flywheel Mass × Radius²) / (2 × Angular Acceleration)
Kennzahlen:
- Schwungradmasse (kg): The mass of the flywheel.
- Radius (m): The radius of the flywheel (distance from the center to the edge).
- Winkelbeschleunigung (rad/s²): The rate at which the flywheel’s rotational speed changes.
This formula provides the torque in Newtonmeter (N·m).
How to Use the Flywheel Torque Calculator
Our Flywheel Torque Calculator tool is designed for simplicity and ease of use. To calculate flywheel torque, you need to input the following values:

Beispielrechnung
To better understand the tool in action, let’s go through an example:
- Flywheel Mass: 5 kg
- Radius0.3 hm
- Winkelbeschleunigung: 2 rad/s²
Mit der Formel:
Flywheel Torque = (Flywheel Mass × Radius²) / (2 × Angular Acceleration)
Flywheel Torque = (5 × 0.3²) / (2 × 2)
Flywheel Torque = (5 × 0.09) / 4
Flywheel Torque = 0.45 / 4
Flywheel Torque = 0.1125 N·m
So, the flywheel torque in this example is 0.1125 N m.
Real-World Applications of Flywheel Torque
Flywheel torque is not just a theoretical calculation—it has practical applications in a variety of fields, particularly in mechanical and automotive engineering. Here are a few areas where flywheel torque plays a key role:
