In residential building sector, the provision of clean water is the one of primary need. The water pump used to do that matter. The technology for renewable energy source, i.e. Solar Water Pumping System (SWPS) will help the society in this sector to decrease the electricity consumption for providing clean water. The SWPS converts the solar energy into electricity. Then, the electricity used to activate...
Rural electrification in an archipelago country like Indonesia is a challenge. Indonesian government has stated that basic need of electricity is 60 kWh, however it is not easy to fulfill it. Fortunately, Indonesia is rich in biomass potency. Therefore, converting biomass energy to electricity might be a solution to the country electricity problem. A simple thermal energy harvesting system comprised...
In this paper, four models of AFPMG (Axial Flux Permanent Magnet Generator) are analyzed and compared to get the best model correspond to highest magnetic flux density that produced by those generators. Before analyzing performance of those models, leakage flux are modeled and analyzed by using magnetic circuit approach to defining the optimal distance of magnet to the magnet on the rotor disk. Therefore,...
This paper aimed to find out a model of 1 kWp flat-quasi linear permanent magnet generator (LPMG) for ocean wave power plant in South Java Ocean. First, a flat-quasi LPMG is modeled based on the wave characteristic at the placement site. The model was then simulated using finite element software of FEMM 4.2. Next, the model was optimized to find out the optimum output power and cogging force. The...
Renewable energy becomes popular lately. It could make the better environment, especially for sea waves that could utilized 2% of world energy demand. Linear generator is one of the alternative method in energy harvesting, especially sea wave. Direct drive linear generator has some topologies, such as single stator — dual translator, and dual stator — single translator. The proposed design were 2...
The south coast of Java Island has significant wave height that allows for wave energy to electric energy conversion. Wave energy converter using permanent magnet linear generator (PMLG) attracting more attention due to its efficiency of the generator and the elimination of translational to rotational motion converter in the generator, but PMLG suffer from electric power losses in the winding. In...
In this paper, sea wave power plant was designed to be applied in southern coast of Yogyakarta, Indonesia. The plant was expected to generate 700 Wp output. It had two components: tubular linear permanent magnet generator (TLPMG) and floater buoy. The buoy and the ocean wave were assumed moving continuously. By this condition, the generator was then simulated using finite element software of FEMM...
This paper aims to look at the distribution pattern of the magnetic topology resulting from two different axial machines which are dual rotor with an internal stator (RSR) axial generator and dual stator with an internal rotor (SRS) axial generator. The simulation was performed with the finite element method software FEMM 4.2 using symmetry analysis which considers all parts of identical geometry...
