<P>PROBLEM TO BE SOLVED: To provide a downsized linear motion generator that has improved power generation output. <P>SOLUTION: In a linear motion generator 1, a movable element 4 having permanent magnets 3 are mounted on an outer circumference of an input shaft 2 that is externally excited so as to reciprocate axially. A case 5 holds the input shaft 2 axially reciprocally. On an inner circumference of the case 5, a stator 7 is mounted which has coils 6 wound around the input shaft 2. An inner circumference of the stator 7 and an outer circumference of the movable element 4 radially face each other with an air gap 8 therebetween. The stator 7 has circumferentially laminated layers of first magnetic steel sheets 10. The first magnetic steel sheets 10 are uniform in thickness, and each have a bend 9 that is bent in a thickness direction. The movable element 4 has circumferentially laminated layers of second magnetic steel sheets 13. The second magnetic steel sheets 13 are uniform in thickness, and each have bends 11 and 12 that are bent in the thickness direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
