Abstract
The use of electrical energy is becoming increasingly important in Indonesia, but the energy used is still dominated by fossil fuels by 87.64 percent. As a result, research is required to develop new energy sources. One of the renewable energies, the presence of a permanent magnet power plant, converts magnetic attraction and repulsion into rotary motion on a shaft to rotate a generator to produce electricity. The mini-permanent magnet power plant is expected to be capable of supplying household-scale electricity. This paper aims to obtain the optimal pattern of magnet location using the basic concept of V-Gate to achieve the highest rotational speed and thus produce a large amount of electric power. The experimental method used in this study entails creating a V-Gate magnetic pattern with a variable magnitude of angle and a base distance to rotational speed. According to the test results, the best angle is 5 degrees, and the best base distance is 24 mm. According to the measurements, the mechanical power generated is 300 Watts.
