A conductive pillar passes through an inner ring of a conductive bearing, an outer wall of the conductive pillar interference fits with the inner ring of the conductive bearing, and an end of the conductive pillar is grounded. In this way, it is ensured that a shaft current on a rotor body is discharged by using the conductive bearing and the conductive pillar, to prevent a main bearing of the motor rotor from being electrically corroded by the shaft current. In addition, the conductive bearing is sleeved on the grounded conductive pillar, so that the inner ring of the conductive bearing can interference fit with the outer wall of the conductive pillar.

  • Publication number: 20140028132
    Abstract: Flywheel systems are disclosed that provide increased energy density and operational effectiveness. A first bearingless motor and a second bearingless motor may be configured to simultaneously suspend the central rotor in a radial direction and to rotate the central rotor. However, certain implementations may have one motor or more than two motors, depending on the design. A plurality of the flywheel systems may be collectively controlled to perform community energy storage with higher storage capacities than individual flywheel systems.

  • Publication number: 20130263599
    Abstract: A thermal magnetic engine and a thermal magnetic engine system are disclosed. The thermal magnetic engine includes a fixed element, a rotation element, working fluid and a fin structure. The rotation element includes a working material. The rotation element rotates relative to the fixed element. The working fluid flows through the rotation element and forms a temperature difference on the working material. The fin structure is disposed on the rotation element. The rotation element rotates along a rotating direction due to the temperature difference on the working material and/or due to the flowing of the first working fluid through the fin structure.
