Abstract: Population growth and housing needs are growing rapidly, causing electricity providers to have to increase electric power capacity. Under these circumstances, innovation of generators or micro scale power plants is needed. This research aims to design Axial Flux Permanent Magnet Generators which have 4 Rotors and 4 Stators. This generator is planned to have a low rotation of 500 RPM with an planned output voltage of 49.7 V with a disc-shaped construction, using a bar magnet and a neodymium-iron-boron NdFeB magnet attached to the material in the form of a disc. This disc is made of acrylic and aluminum as a lightweight base that rotates on its axis to cause a magnetic field to produce electrical energy. In measuring voltage with a speed of 500 RPM and using 4 generators, the highest voltage on generator 1 is 21.10 V with a frequency of 51.70 Hz. In the measurement of no-load multi-stator and multi-rotor generators, an output voltage of 48.1 V is generated with a frequency of 51.70 Hz. In measurements on a multi-stator and multi-rotor generator with a load of 40 W, a voltage of 45.2 V is generated with a current of 0.06 Amperes. At a load of 80 W a voltage of 43.3 V is generated with a current of 0.14 Amperes, while a load of 120 W produces a voltage of 41.5 V with a current of 0.21 Amperes.
