Ducommun's AC induction motors for downhole drilling and gas exploration are used worldwide by prime oil service companies. The performance of our highly reliable motors has continuously improved during the last 20 years to provide unsurpassed lifetimes in extremely harsh operating environments at high temperatures-high pressures (HTHP) up to 232°C (450°F) and 2068 bar (30,000 psi).
These motors are available from size 15 (OD 1.5") to size 38 (OD 3.8"). Our latest developments of high efficiency motors provide additional reliability for an increasingly demanding downhole drilling environment.
The success of high temperature/pressure motors frequently requires units with
exceptionally long and thin motor designs from 1.5" dia. x 9" long to 3.7"
dia. x 14" long without gear heads. Ducommun has invested to acquire the required
tooling and expertise to routinely meet these requirements.
