Since serveral years flywheels appear as attractive devices for storage of energy under kinetic form. The condition for the validity of such a system is to realise sufficient rotation and peripheral speeds. It presents two main aspects: The stresses in the materials of the rotor with the elongation and balance problems - the bearings with wear, friction and power dissipation problems. This lecture concerns a development which was made in the scope of satellite applications and oriented towards high speed momentum wheels ralized with two possible applications: - wide angular momentum for a low mass, energy storage by utilisation of two counter rotating wheels.
