Patent number: 11584498Abstract: An actuator for imparting steering movement to a tiller of a propulsion unit of a marine vessel comprises an absolute position sensor operable to sense a steering position and a relative position sensor operable to sense a position of the motor. A steering control unit calibrates the relative position sensor based on a signal of the absolute position sensor. Calibration of the relative position sensor based on a signal of the absolute position sensor initializes an accumulative position which accumulates a relative position as the actuator moves over time.Type: GrantFiled: March 8, 2021Date of Patent: February 21, 2023Assignee: Marine Canada Acquisition Inc.Inventors: Anson Chin Pang Chan, Ian Michael Carlson, Ray Tat Lung Wong, Mark Isaac Dyck

Patent number: 11433981Abstract: An electric actuator for a marine steering system comprises a housing and an output shaft reciprocatingly received by the housing. There is a rotor disposed within the housing. The rotor is coupled to the output shaft of the electric actuator. Rotation of the rotor causing the output shaft of the electric actuator to reciprocate relative to the housing. There is a motor disposed within the housing. The motor has an output shaft coupled to the rotor. A longitudinal axis of the output shaft of the motor is parallel with a longitudinal axis of the output shaft of the electric actuator. There is also a drive mechanism disposed within the housing. The drive mechanism couples the output shaft of electric actuator to the rotor. The drive mechanism is on a plane radial to a longitudinal axis of the output shaft of the motor. There is an actuator position sensor disposed on the rotor for sensing a position of the rotor. The actuator position sensor senses an actual steering position based on a position of the rotor.Type: GrantFiled: February 12, 2020Date of Patent: September 6, 2022Assignee: Marine Canada Acquisition Inc.Inventors: Anson Chin Pang Chan, Geoffrey David Duddridge, Ian Michael Carlson, Richard Redfern, Mark Isaac Dyck

Patent number: 10988224Abstract: An electric actuator comprises a housing and an output shaft reciprocatingly received by the housing. There is a screw assembly disposed within the housing and coupled to the output shaft. The screw assembly includes a plurality of annular rollers and a central screw received by the annular rollers. The annular rollers are rotatable about the central screw. There is a motor which includes a stator and a rotor. The rotor has an inner bore which engages the annular rollers. Rotation of the rotor causes the central screw to translate axially relative to the rotor and the output shaft to reciprocate relative to the housing.Type: GrantFiled: October 8, 2019Date of Patent: April 27, 2021Assignee: Marine Canada Acquisition Inc.Inventors: Noam Dean Davidson, Ray Tat Lung Wong, Mark Isaac Dyck

Patent number: 10766590Abstract: An outboard motor includes a steering arm that turns around a centerline of a steering shaft together with the steering shaft, a steering actuator including a movable body that moves in a right-left direction, and a motion converter that converts a movement of the movable body in the right-left direction into a turning motion of the steering arm around the centerline of the steering shaft. The motion converter includes a bushing holder into which the steering arm is inserted in a front-rear direction and a bushing interposed between the steering arm and the bushing holder and including an outer surface provided with a pair of first sliding portions each including a convex arc-shaped vertical section that is perpendicular or substantially perpendicular to the right-left direction.Type: GrantFiled: May 13, 2019Date of Patent: September 8, 2020Assignees: YAMAHA HATSUDOKI KABUSHIKI KAISHA, MARINE CANADA ACQUISITION INC.Inventors: Morihiko Nanjo, Noam Dean Davidson, Richard Tyler Redfern, Mark Isaac Dyck, Eric B.
