1. What is a Flywheel Diameter?

Definition: The diameter of a flywheel is the measurement across its circular face, which varies depending on the application.

Purpose: Flywheels store rotational energy and their size affects energy storage capacity and rotational inertia.

2. Typical Flywheel Diameters

Common diameter ranges:

• Car engines: 12-15 inches
• Truck engines: 15-18 inches
• Industrial machines: 20-36 inches or larger

3. Importance of Flywheel Size

Details: Larger diameters provide greater rotational inertia but require more space and stronger materials to handle centrifugal forces.

5. Frequently Asked Questions (FAQ)

Q1: Why do flywheel sizes vary?
A: Size depends on required energy storage, engine/machine size, and RPM range.

Q2: Can I measure my existing flywheel?
A: Yes, measure across the face from edge to edge through the center.

Q3: What affects flywheel diameter choice?
A: Engine power, desired smoothness, space constraints, and material strength.

Q4: Are there standard sizes?
A: While typical ranges exist, exact sizes vary by manufacturer and application.

Q5: How does diameter relate to performance?
A: Larger diameters store more energy but may limit maximum RPM due to material stress.
