The concept of a household low-speed kinetic energy storage

This paper presents a concept of mechanical design, for a slow-speed kinetic energy storage device. It is an attempt to present the problem of using the device to cooperate with small-scale household RES. Calculations allowing for selection of rotating mass along with determination of effective revolutions of the rotating mass are presented. The 3D model gives an overview of the main structural nodes of the device in the mechanical part. Due to large axial load resulting from the mass of the rotor and other components and subassemblies, a simple FEM simulation of the structure base was performed. Preliminary calculations of the magnetic bearing, acting as an axial bearing, were also carried out.
