M32 FLYWHEEL - INSTALLATION & MAINTENANCE MANUAL

1.6 - Safety Features

Amber Kinetics has developed a comprehensive, five-
step approach to flywheel safety. Our methodology
encompasses the entire spectrum from design to
manufacturing, testing, installation, and operation:

•

Design:

Each M32 flywheel is

designed using conservative peak
stress and cyclic fatigue margins
that are consistent with aerospace
engineering standards.

•

Manufacturing:

The material used

for the Flywheel Rotor is produced
using a commercially proven
manufacturing process that yields
the cleanest, highest-grade steel
available.

•

Testing:

Finished rotors are

scanned for both surface and bulk
defects. Each rotor is then spun
beyond its maximum rated
operating RPM before being
placed into service.

•

Installation:

As a redundant safety

measure, M32 flywheels are
installed either below grade or
behind surrounding earth berms.

•

Operation:

Each M32 flywheel is

monitored 24/7/365 by a health
monitoring system.
