*) Required moment of inertia after flywheel is based on 403 Kgm

flywheel, and the most common damper.

The calucation is based on 42% engine acceleration.

Larger flywheel means lower alternator inertia demand, as total GenSet inertia is the final demand.
Selection of bigger flywheel for having lower alternator inertia demand, have to be approved by a torsional

vibration calculation.

The following flywheels are available:

403 Kgm

570 Kgm

801 Kgm

**) Incl. flexible coupling for two bearing alternator.
