  • Electrically controllable pitch propeller system for maritime crafts
    Patent number: 12275514
    Abstract: An electrically actuated propeller pitch control system includes a propeller hub assembly, a propeller assembly, and a crosshead drive system. The propeller hub assembly rotates about the central axis during operation of watercraft. The propeller assembly is configured to selectively rotate a propeller blade. The crosshead drive system includes an electric motor, a transmission, and a lead screw that rotates about the central axis.
    Type: Grant

  • PROPELLER PITCH INDICATOR SYSTEMS FOR ELECTRICALLY CONTROLLABLE PITCH PROPELLER SYSTEMS ON WATERCRAFT
    Publication number: 20250100662
    Abstract: An electrically actuated propeller pitch control system includes a propeller hub, a propeller assembly, and a crosshead drive system. The propeller hub rotates about the central axis during operation of watercraft. The propeller assembly is coupled to rotate with the propeller hub during operation of the watercraft. The crosshead drive system includes an electric motor, a lead screw, and a pitch position indicator system configured to indicate a pitch angle of propeller blades.
