Performance of generator translation and rotation motion on vertical direction for sea wave power plant

Abstract

The generator has been used in the sea wave power plant to converting mechanical energy into electrical energy. Generator for sea wave power plant depends on the motion as translation and rotation. For position of trust force direction is horizontal and vertical motion. Generator translation and rotation consists of several components such as rotor, stator, frame holder of generator, shaft, piston and etc. In previous study, the generator translation and rotation motion in horizontal direction was used for sea wave power plant [1]. The results show that the performance of generator is depend on the stiffness of frame holder of generator, number of coil (pole) and magnet, material of pole and magnet and etc. The design frame holder of generator translation and rotation motion in horizontal direction is less rigid (stable) and precision, thus affecting the performance of the generator. To overcome problem in the frame holder of generator translation and rotation in horizontal direction, frame holder of generator vertical direction mechanism are used in this research and performance of generator is output like output voltage and power of generator. Input power of generator by using manual process (rotated by hand) and rotation speed of thrust force of generator is 100 rpm to 200 rpm and using load by lamp 16.6 ohm (12 w). Generator holder design made with 900 inclination conditions in order to straight or perpendicular to the motion generator components. By applied separate of experimental of generator translation and rotation motion obtained the results of experimental tests voltage generator without the load for generator translation motion is 42.7 volts at 200 rpm and for the generator rotation motion of 77.4 volts. By applied load, the maximum value of output voltage generator becomes decrease is 31.14 volt for generator translation and generator rotation is 36.82 volt.
