The strong points of shaft generators application on board ships are numer-ous and well known to shipowners it's enough to mention that the shaft genera-tor is producing electrical energy with a 20% higher efficiency than the tradi-tional diesel due to lower specific fuel consumption, i. For a rack and pinion, set n=0. IP IP ble up to IP 56. R. In the marine segment, “shaft generator” is defined as the rotation electrical machine that takes power from the main propulsion diesel engine to produce electricity. Smaller 4-stroke auxiliary engines compared to larger 2-stroke main engines are generally less efficient, having a higher fuel consumption resulting in more expensive operations and higher emissions.
The shaft generator has the following characteristics: Creates a shaft from left to right, using different sections. Detailed knowledge of electromagnetic characteristics of shaft … Shaft generator is a clean source of power, which means it does not burn any fuel to generate power, and for the same reason it is also called the green source of power. If a shaft generator is installed and should not be a part of the power calculation, the power limitation function can be set to limit engine power based on inputs from the shaft power metering system (ShaPoLi). Thus as the rotor turns, a voltage is developed on the shaft longitudinally (directly along the shaft). The Switch propulsion motors offer high efficiency with a large speed range. • Optional (benefits to be discussed later).
