• The flywheel rotor was supported by non-contacting magnetic bearings that provide very low frictional losses, It stores energy in a kinetic form,the motor/generator converts mechanical energy to electric form, and vice versa.The flywheel rotor work in a high speed,must be high energy density,high mechanical strength,and dynamics properties.
