Automatic system for anti-roll stabilization of watercraft

Abstract

An automatic system for anti-roll stabilization of watercraft, comprising, a stabilizing fin that can turn about an axis, an actuator assembly, designed to govern rotation of said fin about said axis, and a regulating system, designed to govern said actuator assembly as a function of signals indicating rolling of the watercraft. Said actuator assembly comprises an electric motor connected to said stabilizing fin.

1 . An automatic system for anti-roll stabilization of watercraft, comprising:
 a stabilizing fin that can turn about an axis;   an actuator assembly, designed to govern rotation of said fin about said axis; and   a regulating system, designed to govern said actuator assembly as a function of signals indicating rolling of the watercraft,   wherein said actuator assembly comprises an electric motor connected to said stabilizing fin.   
   
   
       2 . The system according to  claim 1 , wherein said regulating system comprises:
 a sensor designed to supply a signal indicating rolling of the watercraft;   a microprocessor regulating unit, designed to process the data on rolling of the watercraft supplied by said sensor; and   a driving unit for governing said electric motor.   
   
   
       3 . The system according to  claim 2 , wherein said regulating system is arranged for carrying out control of the angular position of the stabilizing fin by means of an encoder associated to said electric motor. 
   
   
       4 . The system according to  claim 2 , wherein the regulating system is arranged for controlling one or more of the following operating parameters of the electric motor: power, torque, speed, position, electrical power input, load. 
   
   
       5 . The system according to  claim 1 , wherein said electric motor is a permanent-magnet d.c. motor. 
   
   
       6 . The system according to  claim 1 , wherein said electric motor is connected to said stabilizing fin via a reduction gear.
