Ducommun’s permanent magnet alternators for downhold exploration tools are used worldwide as a constant source of power replacing batteries. The performance of our highly reliable alternators has been continuously improved over the last 20 years to provide unsurpassed lifetimes in extremely harsh operating environments at high temperatures-high pressures (HTHP) up up to 232°C (450°F) and 2068 bar (30,000 psi).

The available designs range from size 16 (OD 1.6”) to size 40 (OD 4.0”).

The success of high temperature/pressure alternators frequently requires units with exceptionally long and thin motor designs from 1.5” dia x 9“ long without gear heads. Ducommun has invested to acquire the required tooling and expertise to routinely meet these requirements.
