There are two reasons why a PM shaft generator system saves fuel. First, electric power is produced with a vessel''s 2-stroke main engine, which is more efficient than 4-stroke gensets. Second, a PM machine is more efficient than conventional machines. Often, it is also common to use a controllable-pitch propeller (CPP).

There has been some confusion over the energy stored in a permanent magnet, with many texts and some finite element packages giving incorrect values. We demonstrate the correct formulation, under both normal operation and partial demagnetization, and discuss the physical meaning of stored energy in a permanent magnet.
