Perancangan Generator Magnet Permanen Fluks Aksial Putaran Rendah

This research was conducted to resolve the problem electric energy crisis by developing a small-size generators using permanent magnets neodymium ferrite boron (NdFeB), which can be used as device to utilized renewable energy. Three phase axial flux permanent magnet generator (AFPMG) was designed which has low speed, with double rotor and single stator. This generator is deemed most appropriate because in addition to only requiring low speed, but also a relatively low manufacturing cost, lightweight construction, and a more compact form which can support better utilization of renewablwe energy such as microhydro or wind. The test results obtained by that generator capable of generating electricity 50 Hz at 250 rpm and generates voltage of each phase R, S, and T, respectively is 18,25; 18,15; and 18,66 volt at no load condition and by varying the frequency value at 20 Hz to 75 Hz, generating phase voltage is 7,35 volt up to 28,06 volt. When the resistive load testing, the generator is able to generate the power is 28,99 watt at 50 Hz. By varying the frequency from 30 Hz to 70 Hz, acquired the power is 3,16 watt up to 57,29 watt
