碩士 / 國立臺灣海洋大學 / 電機工程學系 / 103 / Taiwan is lack of natural resources because it is an island, and it’s a trend to exploit renewable energy resources. The known renewable energy resources of develop values are solar energy, geothermal energy, marine energy, biomass energy, wind energy, etc. The research purpose of thesis is to build a valid Mechanics-electricity transformation device for near shore power generation. It would be more efficient than other medium transforming kinetic energy to electricity. The generator models with different specification were constructed by the Maxwell software and the magnetic flux density distribution was obtained. By using the calculation tool, Matlab, the computation analyzes of its induced EMF and the average power from the build module construction. In the analogue result, the linear generator possible optimization specification was found out, and the simulation test was carried out effectively and accurately in the personal computer.
By the Faraday induced EMF law, designed a structure with the magnetic-flux density dramatic change which induced the coils’ large magnetic flux variation while coils moving. The structure was composed by 4 to 7 magnetic elements which were placed parallel. There was a void with a pair of magnet bars in the middle of the single rectangle element. The parallel arrangement can extend the magnetic flux density to the each other elements and enlarge the magnetic path and magnetic field strength. The coils size was decided by the magnetic flux density distribution, and the optimization of the elements distance can be found. As the result from the simulation, the largest device’s power occurred if the total length of the structure is 28 cm, the 4 cm width element with 0.2 cm lateral distance between magnets. A device prototype with 4 cm width elements was built and the measured magnetic flux density variation was similar with the simulation. When the moving speed of the coil reached 1.53 meter per second, the peak of the induced magnetic voltage was 0.2 Volts and the average power was 0.82172 watt. According to the turns for the coil were 400, the maximum voltage of the prototype was about 100 Volts.
