AUV and ROV thruster
Brushless DC Saab Seaeye

Saab Seaeye was the first manufacturer to successfully introduce reliable brushless DC motor technology for ROV propulsion and won technology awards for its thruster innovations. Part of this development was to incorporate the drive circuitry within the thruster housing. Today, all Seaeye thrusters incorporate:

* Closed loop velocity feedback for precise response to input commands
* Self contained drive electronics within the thruster housing
* Titanium shafts for lightness and strength (on all thrusters but the SM8)
* Angular contact thrust bearings for longer life
* Fouled propellor detector and reset circuitry
* Under voltage protection of the electronics
* Tungsten carbide shaft seals
* Integral pressure compensation for full ocean depths of operation
