    The purpose of flywheel energy storage system (FESS) is to store unused nighttime electricity as kinetic energy and convert it to electricity during daytime. The FESS is proposed as an effcient energy storage system because there is no mechanical problems, such as friction and wear. The flywheel is rotated at a high speed, 10,000 rpm. The rotor dynamic analysis should be performed with a adequate analytical model and equations of motion to identify the stable driving condition and the dynamic behavior. But the analysis has to be needed for a long time to get the result from solving software that is used 3D model because the number of node and element is very big for good result. Therefore, in this paper, the new modelling method using 2D model is suggested. It will be solved by coded program in MATLAB by FEM(Finite Element Method). And the result from coded program is compared with results from common solving software, MSC. Nastran and ANSYS Workbench.
