Design process and optimisation of an integrated electromechanical battery

摘要

As part of an electromechanical battery design project using flywheels, we present here the results of a research on solutions with low Cost price and high energy density. The energetic characteristics formalisation helps us to choose and design a suited structure integrating a motor-generator and magnetic bearings. The rotor design requires to take into account the mechanical and electromechanical coupling as a function of the assembly technology. The converter optimisation is based on geometric modification and optimised numerical models.
