A magnetically suspended flywheel system comprises a housing, a stator assembly, and a rotor assembly. The stator assembly comprises a ring-shaped stator magnet having a substantially triangular cross section. The rotor assembly comprises a vertical shaft, a cone-shaped rotor magnet having a substantially triangular cross section, and a flywheel. The ring-shaped stator magnet has the same sense of magnetisation as the cone-shaped rotor magnet. The ring-shaped stator magnet forms inverse heart-shaped magnetic flux lines, and the cone-shaped rotor magnet forms heart-shaped magnetic flux lines. An upward magnetic repulsion force between the inverse heart-shaped magnetic flux lines of the ring-shaped stator magnet and the heart-shaped magnetic flux lines of the cone-shaped rotor magnet equals a downward gravitational force by the rotor assembly in order to passively suspend the rotor assembly so that the rotor assembly is capable of rotating around the central axis of rotation. This invention relates to flywheel systems, and the principal use of the invention is for kinetic energy storage systems.
Système de volant suspendu magnétiquement comprenant un boîtier, un ensemble stator et un ensemble rotor. L'ensemble stator comprend un aimant de stator annulaire dont la section transversale est essentiellement triangulaire. L'ensemble rotor comprend un arbre vertical, un aimant de rotor conique dont la section transversale est essentiellement triangulaire et un volant. L'aimant de stator annulaire est aimanté dans le même sens que l'aimant de rotor conique. L'aimant de stator annulaire produit des lignes de champ magnétique en forme de cour inversé et l'aimant de rotor conique produit des lignes de champ magnétique en forme de cour. La force de répulsion magnétique ascendante, entre les lignes de champ magnétique en forme de cour inversé de l'aimant de stator annulaire et les lignes de champ magnétique en forme de cour de l'aimant de rotor conique, est égale à la force de gravitation de l'ensemble rotor, afin de suspendre passivement l'ensemble rotor pour qu'il puisse tourner autour de l'axe de rotation central. L'invention concerne des systèmes de volant et est principalement utilisée dans des systèmes de stockage d'énergie cinétique.
