Abstract

A magnetic suspension energy-storage flywheel system being a energy-storage device for spacecrafts mainly consists of an axial mixed magnetic bearing, a protection bearing, a radial / axial integrated displacement transducer, a rotor of high-strength composite material, a motor / generator, a radial mixed magnetic bearing, a casing, a mounting shaft and a lock nut. The motor / generator and the mounting shaft is in the middle of the flywheel, and outward are the radial mixed magnetic bearing, the radial / axial integrated displacement transducer, the protection bearing, the axial mixed magnetic bearing and the lock nut in order. The rotor of the high-strength composite material lies outside of the radial mixed magnetic bearing. The integral system is sealed in the casing.

Description

Technical field

[0001] The invention relates to a magnetic levitation energy storage flywheel system, which can be used as an energy storage device for spacecraft such as satellites, earth observation platforms, spacecraft, space shuttles, and lunar vehicles, as well as storage batteries, uninterruptible power supplies, electric vehicles, trains, etc. The power source of the vehicle. Background technique

[0002] The energy problem is one of the main constraints to the short life and low reliability of spacecraft such as satellites, earth observation platforms, spacecraft, and space telescopes. Improving the supply capacity, life, and reliability of power supplies is the core issue that needs to be solved urgently for spacecraft. At present, the chemical batteries used in spacecraft have low energy density, limited service life, unstable working performance, and uncertain power. Compared with them, the maglev energy storage flywheel has high energy storage density, high peak...
