Vibrate generator is an electric generator, which generate electric by a magnet vibration. This research inspired by the discovery of windbelt by Humdinger. The purpose of this research is to prove electric generator with magnetic vibration, to design low rpm vibrate generator. Electric generator in this vibration is simple, expected to be made society with local material. With an energy source from a ditch drainage or wind, this generator are supposed to generate electricity for one house. Major component generators are bar magnets, springs, wire coils, diode, capasitor and wood board. The principle of generator unit is a magnet attached to the spring and the end of the spring attached to the wooden board.  If the spring is vibrated, magnetic vibrations produce a magnetic flux change that penetrates the wire coil who attach beside a magnet. A wire coil penetrated flux magnetic which change with time to produce electro motive force. Every unit generator produce AC and changed to DC by Diode Bridge. The experiment results were one unit cell generator produce 2.2 volt peak to peak, 21.47 Hz, and product duration 0.5second. The design of a low rpm vibrator generator is built from a vibration generator unit arranged and connected in parallel. Each unit vibration generator is vibrated sequentially, in order for a continuous power generation.

The Impact

In this study, the axial flux permanent magnet motor and the length range of the air gap between rotors was analyzed and the appropriate length obtained. NdFeB permanent magnets were used in this study. Permanent magnets can change the characteristics of the motor's torque. However, the distance between permanent magnets and the air gap will remain constant for each magnet. The impact of different magnet angles for the axial flux permanent magnet motor and other motor parameters was examined. To this aim, the different angles and torque values of the magnetic flux density were calculated using the finite element method of analysis with the help of Maxwell 3D software. Maximum torque was obtained with magnet angles of 21°, 26°, 31.4°, and 34.4°. Additionally, an important parameter for the axial flux permanent magnet motor in terms of the air gap flux was analyzed. Minimum flux change was obtained with a magnet angle of 26°. The magnetic flux of the magnet-to-air-gap is under 0.5 tesla. Given the height of the coil, the magnet-to-air-gap distance most suitable for the axial flux permanent magnet motor was 4 mm.

Abstract The control systems for the objects of industry, power generation, transport, etc. are extremely complicated; functional efficiency of these systems determines to a great extent the safe and non-polluting operation as well as convenience of service and repair of such objects. The authors consider the possibility to improve the efficiency of systems for damping oscillations in transport using a combination of electrical (generators of rotational and linear types) and hydraulic means. Better efficiency of functioning is achieved through automatic control over the operational conditions of such a system in order to make it adaptive to variations in the road profile and ambient temperature; besides, it is possible to produce additional electric energy.

Simulation Results

The power converter connected to energy source and linear electric generator is crucial powertrain and converting component, and it is mainly used in hybrid electric vehicle. For switching the states of release energy and absorb energy quickly and smoothly, the accuracy of converter model is very important for designing of control system. The performances of converter can be evaluated by modeling and simulation before produce actual circuitry, so the converter model is created in average model switch network. Simulation results have a distinction between the two models with average model switch network and state equations separately. In comparison the average model switch network is more identical to practical system, so it is more valid for guiding design of control system of converter.

Rice husk is biomass that can be utilized as fuel for biomass gasification as a renewable energy source. In this paper, thermochemical methods were used to determine the higher heating values, moisture content, bulk density, pellet density, microstructure, and elemental composition of Thai Rice Husk (Oryza Sativa Linn). The heating energy was analyzed using a bomb calorimeter, which showed a higher heating value of 15.46 MJ/kg. Determination of pellet density through rice husk powder pelletization exhibited a value of 1.028 g/cm3, while moisture content was 5.017 wt%. The heating value and moisture content revealed good agreement with the literature values, indicating the potentiality of rice hush for energy generation. Scanning electron microscopy (SEM) showed that the raw rice husk and its ash have similar porosity types but different bulk structure.  Elemental analysis using energy dispersive X-ray (EDX) indicated that rice husk contains O, Si, C while O and C percentages were drastically decreased during combustion. The obtained heating value and moisture content proved that rice husk could be used as a bio-energy source in biomass gasification for power generation.
