Abstract
- Electrical machines in downhole operations must operate at harsh environmental conditions. Therefore, compared to common machines, they often fail which can lead to pausing or stopping a drilling job. - The proposed three-phase machine design uses a concentrated armature winding with separated phase coils and hydrolysis-resistant wire insulation. - Compared to a distributed armature winding, this simplified design is easier to manufacture, such as with additive manufacturing, and less damaging to the wire insulation. It offers a high level of protection against chemical reactions that can disrupt machine operation. - This design offers a significant improvement to the machine’s lifetime expectation, while still offering a high winding factor and a high-power density.
