SYSTEM AND METHOD FOR DOWNHOLE POWER GENERATION USING A DIRECT DRIVE PERMANENT MAGNET MACHINE |
| 摘要 |
A system and method for generation of electrical energy by a downhole tool in a wellbore. A downhole tool for use in a wellbore includes a housing and a power generation system disposed within the housing. The power generation system includes a power section and an axial flux generator. The power section is configured to convert flow of drilling fluid through the downhole tool to rotation. The axial flux generator is coupled to the power section. The axial flux generator is configured to produce magnetic flux that extends parallel to an axis of the rotation, and to generate electrical energy responsive to the rotation. |
