Sub-Atlantic Brushless DC Electric Thrusters

Sub-Atlantic’s new direct drive range of brushless DC thrusters break new ground in thrust, low weight and enhanced reliability. They are currently available in three sizes, each incorporating Sub-Atlantic’s unique StatorshieldTM technology.




Sub-Atlantics unique Statorshield™ system allows the thruster to continue running in the event of a shaft seal failure and subsequent flooding, without damage to the winding or electronic components. Integral electronic drives are oil filled and pressure compensated to 3000 metres / 10,000 feet. Three sizes are available with propeller diameters up to 246mm / 9.7” and bollard thrusts up to 100 kgf / 220 lbf.
