This study aims to observe the influence of the changing stator dimension on the air gap magnetic flux density (Bg) in the design of a single-phase radial flux permanent magnet generator (RFPMG). The changes in stator dimension were carried out by using three different wire diameters as stator wire, namely, AWG 14 (d = 1.63 mm), AWG 15 (d = 1.45 mm) and AWG 16 (d = 1.29 mm). The dimension of the width of the stator teeth (Wts) was fixed such that a larger stator wire diameter will require a larger stator outside diameter (Dso). By fixing the dimensions of the rotor, permanent magnet, air gap (lg) and stator inner diameter, the magnitude of the magnetic flux density in the air gap (Bg) can be determined. This flux density was used to calculate the phase back electromotive force (Eph). The terminal phase voltage (V∅) was determined after calculating the stator wire impedance (Z) with a constant current of 3.63 A. The study method was conducted by determining the design parameters, calculating the design variables, designing the generator dimensions using AutoCad and determining the magnetic flux density using FEMM simulation.  The results show that the magnetic flux density in the air gap and the phase back emf Eph slightly decrease with increasing stator dimension because of increasing reluctance. However, the voltage drop is more dominant when the stator coil wire diameter is smaller. Thus, a larger diameter of the stator wire would allow terminal phase voltage (V∅) to become slightly larger. With a stator wire diameter of 1.29, 1.45 and 1.63 mm, the impedance values of the stator wire (Z) were 9.52746, 9.23581 and 9.06421 Ω and the terminal phase voltages (V∅) were 220.73, 221.57 and 222.80 V, respectively. Increasing the power capacity (S) in the RFPMG design by increasing the diameter (d) of the stator wire will cause a significant increase in the percentage of the stator maximum current carrying capacity wire but the decrease in stator wire impedance is not significant. Thus, it will reduce the phase terminal voltage (V∅) from its nominal value.

The purpose of this research is to know to know the influence of stator coil shape to performance (induced voltage and output power) of single phase axial flux permanent magnet generator. The method used is an experimental method. The population in this study is a unit of single phase axial flux permanent magnet generator. The sample in this study is the stator coil. Experiments were carried out by testing the performance of a single-phase axial flux permanent magnet generator in each variation the number of coil windings which had the 90 turns, 120 turns, and 350 turns. Experiments were carried out with no -load testing and with a resitive load that used 30 Watt incandescent lamps. The conclusion of this study shows that there is an influence from the number of coil windings on the performance (induced voltage and output power) of the generator. From three variations of the stator coil that used as sample, the highest performance is shown by the single phase axial flux permanent magnet generator which used the highest number of coil stator turns. The more number of turns, the better the performance of a single-phase axial flux permanent magnet generator. Abstrak Tujuan dari penelitian ini adalah untuk mengetahui pengaruh jumlah lilitan kumparan stator terhadap kinerja generator fluks aksial satu fasa yang berupa tegangan induksi dan daya listrik yang dihasilkan.
