Shaftless, Magnetically Levitated Flywheel Energy Storage Systems
MagneMotion, Inc.Acton MA
ACCOMPLISHMENTS Burst tested to 79,500 RPM.
32% higher than design speed. Rotor / System tested to 36,000 RPM.
Flywheel was very stable. Bearing losses need to be examined in greater
detail.
COMMERCIALIZATION Linear synchronous motors and maglev are the core
of MagneMotion's business. Applications in that arena include providing high peak
power for short periods of time, something that is hard to do with batteries.

GOVERNMENT/SCIENCE APPLICATIONS When used for both energy storage and attitude control
the system has the potential to be lighter, more efficient and with a longer life expectance than is possible with conventional alternatives.
Results are promising but further development is required to create a mission-ready design.
MagneMotion is in negotiation with established energy storage company to team for continuation.

INNOVATIONA maglev flywheel with a shaftless carbon fiber rotor that requires
only one axis of active control. The shaftless design eliminates resonances over a wide operating speed range, so the flywheel is
usable for both energy storage and attitude control.
