Variable-Output Generator for Downhole Power Production |
| 摘要 |
Methods and systems of downhole power generation are disclosed. The method includes the steps of rotating a magnet assembly about an axis relative to a coil assembly at a first rotational velocity, axially moving the magnet assembly to a first position on the axis with a configurable actuator so as to adjust a magnetic interaction between the magnet assembly and the coil assembly, and providing a power output from the coil assembly at a first power output level corresponding to the first position while the magnet assembly is rotating at the first rotational velocity. |

1. A method of downhole power generation, comprising:
rotating a magnet assembly about an axis relative to a coil assembly at a first rotational velocity; axially moving the magnet assembly to a first position on the axis to adjust a magnetic interaction between the magnet assembly and the coil assembly; and providing a power output from the coil assembly at a first power output level corresponding to the first position while the magnet assembly is rotating at the first rotational velocity. |
