Claims13
A radial-axial one-piece magnetic bearing for an energy storage device, comprising:
- a bearing rotor, with an axis extended in an up-down direction and provided, at a lower end of the bearing rotor, with an annular rotor magnetic steel extended along a circumferential direction of the bearing rotor;
- and
- a bearing stator, arranged below the bearing rotor and formed with a recess at an upper end face of the bearing stator, wherein the lower end of the bearing rotor is fit in the recess, an annular stator magnetic steel extended along the circumferential direction of the bearing stator is positioned at a wall of the recess, at least part of the annular stator magnetic steel is opposite to the annular rotor magnetic steel in the up-down direction and positioned below the annular rotor magnetic steel, and at least part of the annular stator magnetic steel is opposite to the annular rotor magnetic steel in a radial direction of the bearing rotor, wherein the annular rotor magnetic steel repels the annular stator magnetic steel.
