Marine electric propulsion is made up of Marine prime mover groups (diesel generator set, gas turbine generator set, steam turbine generator set and fuel
The output electrical energy is then driven by the motor to drive the screw, water jet propeller, pod propeller, and straight wing propulsion
There are many types of thrusters, so as to provide forward propulsion for the ship.
1. Technical characteristics of Marine electric propulsion system
Marine electric propulsion usually includes DC propulsion and AC propulsion. There are currently three major electric propulsion systems in the world
They are shafting propulsion system, francium propulsion system and pod propulsion system.
(1) In the shafting propulsion system, the variable speed motor usually drives the screw, and the direct connection between the variable speed motor and the screw shaft can be used
Connection mode or through a gear device: the motor is connected to the spiral shaft.
(2) The all-round propulsion system can achieve free rotation, and can produce thrust in any direction, and its thrust can be adjusted by constant speed
Pitch screw or variable distance control. Motors inside a francium propulsion system usually include two types of horizontal motors
+Z gear drive, vertical motor +L gear drive. Omnidirectional propulsion systems usually cannot be turned in reverse to produce
Push.
(3) The pod propulsion system can rotate freely and produce a push in any direction
Force. The propulsion system integrates the motor with the screw prize in a closed pod device, and the fixed distance screw prize is directly installed in the electricity
Machine shaft _ on [5]. The transmission efficiency of the pod propulsion system is higher than that of the all-directional propulsion system and its mechanical structure is relative
Easy. The pod propulsion system can adopt both push pods and pull pods.
