The invention discloses a ship electric propulsion
system. The ship electric propulsion
system is characterized in that a speed regulation control device
control signal of a speed regulation control module is supplied to a driving operation control module by a speed setup device and a console controller through a
field bus, and information can be controlled to be displayed in a display unit; the speed regulation control device
control signal of the speed regulation control device is supplied to an
engine room operation control module by an
engine room in-place controller through the
field bus, and information can be controlled to be displayed in an indicating unit; a magnetic coupler of the speed regulation control module is controlled by the speed regulation control device through a speed regulation
actuator; and a power propulsion module is formed by a steering controller, an
electric motor, a propulsion device and a speed sensor, the
electric motor is connected with the propulsion device through the magnetic coupler, and the speed sensor is used for detecting the rotating speed and feeding back the rotating speed to the speed regulation control device. According to the ship electric propulsion
system disclosed by the invention, the
electric motor is flexibly connected with the propulsion device, the regulation on load rotating speed and torque is realized,
vibration transmission and
noise superposition are avoided, the service life of components is prolonged, the maintenance cost is reduced, and the stable running of the ship electric propulsion system is ensured.
