Title:
BALANCE ADJUSTMENT DEVICE AND BALANCE ADJUSTMENT METHOD FOR POWER STORAGE DEVICE
Document Type and Number:
Japanese Patent JP2014147163
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To make it possible to rapidly perform dynamic balance adjustment work in a short time, by making it possible to keep dynamic balance of a rotor under a state of a very low temperature and high vacuum.SOLUTION: A power storage device which includes a superconductive magnetic bearing for supporting a rotation axis 7 of a flywheel 8 installed in a container 17 in a non-contact manner and stores electric energy as kinetic energy by making the flywheel 8 in the container 17 under a state of a very low temperature and high vacuum operate rotationally through the superconductive magnetic bearing comprises: a balance weight 100 detachably and/or movably attached to the flywheel 8 ; and adjustment means 101 for operating the balance weight 100 from the outside of the container 17.
