Our Plan

• Construct an Induction based flywheel.
• We are going to build this using Faradays Law
  and Lenzs Law
• During the 5 minute standing time the only losses
  will be to inefficiency in the bearings.

What is the commutator?

• Changes field direction from each coil to insure
  the motor is always experiencing a magnetic
  torque that will keep it rotating.
• Three separate plates that are attached to the
  different induction coils cause the current to
  move through the coils in different directions.
• Brushes are attached to take the current from the
  solar panel to the flywheel

How is the flywheel started?

• Essentially building an electric motor

Using a Emf of 12 volts, assuming there are 100
coils of wire, a magnetic field of 1 x 10 -3 T,
and a surface area of .375 m. The calculated
angular velocity of the flywheel will be 320
radians per second. This is approximately a speed
of 3060 RPM.

Applications

• In supplying components and machines with high
  output voltages when there is a power surge or a
  shutdown
• Currently NASA for Aerospace Flywheel Development
  Program is using flywheels in storing energy
  more efficiently and Improvements in Pointing
  Control

Flywheel by NASA

• On December 2000, Research engineers at NASA
  Glenn Research Center and at U.S. Flywheel
  Systems, Inc achieved full-speed operation at
  60,000 revolutions per minute (rpm).
• On the International Space Station, electricity
  from solar arrays will run the motor that spins
  the wheel. Then, during the shade period of the
  orbit, the spinning wheel will turn the motor,
  now acting as generator, to make the electricity
  that powers science equipment and life support
  systems.
