Problems solved by technology

With the development of science and technology, the requirements for the energy storage and energy storage density of the magnetic levitation energy storage flywheel are constantly increasing, which makes the flywheel rotor store ultra-high kinetic energy, and the risk of damage is extremely strong. It is particularly important to improve the safety protection of the flywheel rotor The safety protection of the magnetic levitation energy storage flywheel includes software control detection and equipment hardware protection, such as motor brakes and magnetic levitation bearing protection bearings, etc. However, when the high-speed and large-mass rotor is damaged, due to the large amount of energy stored in the flywheel rotor, it needs release, relying solely on the shell of the equipment itself cannot form a reliable protection, and it is very easy to explode and cause personal and property losses
