Shaftless, Magnetically Levitated Flywheel Energy Storage Systems
MagneMotion, Inc.
Acton, MA
|
INNOVATION
A 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

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.
