Abstract
The present disclosure provides a device for storing energy, including: at least one electric machine, which is of the Lorentz generator or motor type and has a rotor and a stator, the rotor forming a flywheel; at least one magnet secured to the rotor; and at least one magnetic flux closure. The stator is wound and devoid of ferromagnetic material, and the magnetic flux closure is mounted such that it can move in synchronous rotation with the magnet of the rotor.
Claims10
An energy storage device comprising:
- a rotor forming a flywheel;
- at least one Lorentz-type electric motor/generator comprising the rotor, a wound stator devoid of ferromagnetic material and at least one magnet fixed on the rotor;
- and
- at least one means for closing a magnetic flux,
- wherein the magnetic flux closing means is movably mounted in synchronous rotation with the magnet of the electric motor/generator.
