Testing Low rpm BLDC Generator as Power Plant for Remote Areas

Abstract

BLDC generator can be an alternative solution for providing electricity to rural communities in Indonesia. In this research, a BLDC generator with a rotor and stator frame made from PETG material has been made using 3d printing. The dimensions of the generator stator section are 20 cm x 30 cm x 20 cm. On the inside, there is a magnetic wheel with a radius of 20 cm and a height of 3 cm. The coil used on the rotor is a coil of copper wire with a thickness of 0.4 mm and on each coil, there are 1250 turns. The research objective is to study the characteristics of generators at low speed for the application of electricity supply to rural communities. These characteristics are obtained from test results using a coupled generator and test motor. The test results show that at a low speed of 200 -900 rpm, an increase in BLDC generator rpm will cause an increase in power. Testing the power load on the generator at 900 rpm with a variation of resistance of 0.25-15 Ω obtained the highest power of 13.17 W at a resistance of 6 Ω.

Archimedean Screw Based Micro Hydro Power Plant (MHPP) Prototype with Turbine Elevation Angle Parameters

“…This paper will discuss the results of making a micro-hydro power plant prototype and study the effect of the turbine elevation angle on the characteristics and performance of a micro-hydro power plant. The results of this study will complement the results of previous studies conducted by the authors and other researchers [17][18][19][20]. Compared to previous studies, the novelty of this study is that a micro hydro power plant prototype has been made according to the conditions applied in the field (not laboratory conditions).…”
