Document Type and Number:
WIPO Patent Application WO/2023/138575
Kind Code:
A1
Abstract:
A radial-axial integrated magnetic bearing for an energy storage device, comprising a bearing rotor (1) and a bearing stator (2). The axis of the bearing rotor extends in an up-down direction; the lower end of the bearing rotor is provided with an annular rotor magnet (3) extending along the circumferential direction of the bearing rotor; the bearing stator is located at the lower end of the bearing rotor; a recess (21) is formed in the upper end face of the bearing stator; an annular stator magnet (6) extending along the circumferential direction of the bearing rotor is provided on the wall surface of the recess; at least a portion of the annular stator magnet is opposite to the annular rotor magnet in the up-down direction and is located below the annular rotor magnet, and at least a portion of the annular stator magnet is opposite to the annular rotor magnet in the radial direction of the bearing rotor; the annular rotor magnet and the annular stator magnet repel each other. Further disclosed is an energy storage device comprising the radial-axial integrated magnetic bearing.
