Abstract

A reciprocating power generating module is disclosed, which comprises: a guide; a magnet, being an integrated unit composed of at least two magnetic elements connected with each other in a manner that poles of any one of the plural magnetic elements are orientated to repel poles of its neighboring magnetic elements; and a coil, being wound around the guide; wherein the magnet is capable of being driven to move linearly by the defining of the guide. The full sine-wave AC voltage output is obtained when the relative linear motion equals double of the length of the magnetic element.

Claims

1. A reciprocating power generating module, comprising:

a guide;

a magnet, being an integrated unit composed of a plurality of magnetic elements aligned one next to another in a manner that poles of any one of the plural magnetic elements are orientated to repel poles of its neighboring magnetic elements; and

a coil, being wound around the guide;

wherein, the magnet is capable of being driven to move linearly by the defining of the guide; and

the magnet and the coil is being arranged in a manner selected from the group consisting of;

receiving the magnet inside the guide while arranging the coil outside the guide, and receiving the coil inside the guide while arranging the magnet outside the guide.

2. The reciprocating power generating module of claim 1, wherein each magnetic element is an anisotropic magnet.

3. The reciprocating power generating module of claim 1, wherein the magnet is being received inside an accommodation space formed in the guide while arranging the coil to be wound on the outer wall of the guide.

4. The reciprocating power generating module of claim 3, further comprising:

a back iron, being arranged outside the coil while surrounding the same.

5. The reciprocating power generating module of claim 1, wherein the guide are attached by an elastic member and a buffering member respectively at the two ends thereof.

6. The reciprocating power generating module of claim 1, wherein the guide are attached by magnetic objects respective at the two ends thereof in a manner that the magnetic objects repel the two ends of the magnet.

7. The reciprocating power generating module of claim 1, wherein the guide are attached by weights at the two ends thereof.

8. The reciprocating power generating module of claim 1, wherein the coil is a multi-cell coil having a plurality of sub-coils being defined in the cells thereof in a manner that each sub-coil is wound on the guide by a loops selected from the group consisting of a clockwise loop and a counterclockwise loop.

9. The reciprocating power generating module of claim 1, wherein the coil is a multi-cell coil having a plurality of sub-coils being defined in the cells thereof in a manner that the plural sub-coils are wound on the guide following the same direction while being connected to each other by a manner selected from the group consisting of a serial connection and a parallel connection.

10. The reciprocating power generating module of claim 1, wherein the coil is wound for enabling a single-phase output.

11. The reciprocating power generating module of claim 1, wherein the coil is wound is wound inside out for enabling a two-phase output.

12. The reciprocating power generating module of claim 1, wherein the coil is wound is wound inside out for enabling a three-phase output.

13. The reciprocating power generating module of claim 1, wherein a magnetic material is disposed at a position between any two neighboring magnetic elements to be used for altering the type of flux path.

14. The reciprocating power generating module of claim 1, wherein a soft magnetic material is disposed at a position between any two neighboring sub-coils for enhancing the affection of magnetic flux variation upon the coil.
