Counter Rotating Motor
   The underwater counter rotating propulsions have two fans which rotate opposite each other.

    The efficiency of counter rotating hydrodynamic systems often is 15% more than those have one fan.

    Special design motors, AC or DC are used for counter rotating systems. 
   
These kinds of motors have two inner and outer shafts that they rotate in the opposite directions simultaneously, which are particularly suitable for under water propulsion systems.

    
The nominal power of these motors is 38, 60 and 72 KW.
