<P>PROBLEM TO BE SOLVED: To reduce weight of a generator stator in a fluid power generator where the generator stator is moved linearly. <P>SOLUTION: A generator rotor 12 has a plurality of permanent magnets 31 that are arranged in such a manner that north and south poles are alternately formed around a central line. A generator stator 14 has: a plurality of cores 17a arranged so as to face the permanent magnets 31, respectively; and a plurality of coils 18 wound around the cores 17a, respectively. When the generator stator 14 is moved linearly by a stator driving device 13, weight P1 of the generator stator 14 is reduced by magnetic attractive force P2 between the permanent magnets 31 and the cores 17a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
