High Temperature & Pressure AC Induction Motors

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 been continuously improved over 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).

The motors are available from size 15 (OD 1.5”) to size 38 (OD 3.8”).

Description

Our latest developments of high efficiency motors provide additional reliability for the 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.
