The principle of marine generators is basically the same as that of general generators. Marine generators typically use AC generators. Below is a brief introduction to the principles of marine generators.
1. Magnetic Field Generation and Rotor-Generated Electromotive Force
A marine generator consists of a rotor and a stator. The stator has three windings: a potential winding, a current winding, and an excitation winding. When the excitation winding is energized, the magnetic field it generates and the action of the potential winding generate an electromotive force within the rotor.
2. Working Principle of an Electric Motor
A marine generator contains a rotating rotor, driven by an electric motor. The conductor on the rotor rotates in the magnetic field, causing electrons within the conductor to move, creating a potential difference and generating current. This is also how the output current of the marine generator is generated.
