Seaeye Brushless DC Thrusters
Saab Seaeye was the first manufacturer to successfully
introduce reliable brushless DC motor technology for ROV
propulsion in the mid 1980s and won technology awards for
their 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
- 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
Two models are currently available, the Seaeye
SM4 and Seaeye SM5, with new models due for release later
this year.
