Abstrak: Pada penelitian ini, telah dilakukan investigasi pengaruh bentuk geometri dan magnetik flux density terhadap outputtegangan dari generator axial flux magnet permanen. Model dari generator axial didesain menggunakan sofware 3D StudioMax dan visual basic net express. Pada simulasi dan eksperimen digunakan magnet permanen NdFeB yang dibentuk circulardan rectangular dengan variasi magnetik flux density 0,5; 0,8; 1,1; 1,3 Tesla pada kecepatan rotasi sekitar 260 – 540 rpm. Darihasil simulasi dan eksperimen ditunjukkan bahwa geometri magnet permanen sangat mempengaruhi dalam menghasilkanmagnetik flux density maksimum. Hasil ini juga menunjukkan adanya korelasi antara output tegangan maksimum denganmagnetik fluk density maksimum. Semakin besar magnetik fluk density dan kecepatan rotor putar (rotasi) akan menghasilkanoutput tegangan yang semakin besar.Kata kunci: generator, magnetic flux density, rotasi, voltageAbstract: In this paper, the influence of geometric shapes and magnetic flux density on the maximum Voltage (Emax) of theaxial flux permanent magnet generator has been investigated. Modeling of axial flux permanent magnet generator wasdesigned using 3D Studio Max and visual basic net express software. The simulation and experimentally were performed byusing NdFeB permanent magnet in the form of rectangular and circular shape with various Magnetic Flux Densities as 0.5,0.8, 1.1, and 1.3 Tesla at the rotation speed around 260-540 rpm. The obtained results both from simulation and experimentshow that the magnetic geometry, in this case the cross-section A, is directly proportional to the maximum magnetic flux,(Фmax). The results also showed that there was a correlation between the maximum Voltage (Emax) and the maximum magneticflux, ((Фmax). The increasing of magnetic flux density and rotor rotation increases the output voltage.Keywords: generator, magnetic flux density, rotation, voltage

Flux Leakage

Objective:In this study, improvement of power density by applying novel shape of slit and notch to outer ribs of a rotor that reduces magnetic flux leakage in outer rib and increases air-gap magnetic flux density for spe PMSM for a washing machine, was investigated.Methods:It is important that motors for home appliance require lower manufacturing cost, high power and high efficiency. In order to increase power, rotor shape is re-designed. In the outer rib of the rotor, magnetic flux leakage occurs by permanent magnet and magnetic flux is saturated which is one of the factors that reduces the power and efficiency. However, if the outer rib is designed to be too thin, the permanent magnet may scatter during high-speed rotation. Therefore, a design considering permanent magnet scattering is necessary. Motor for a washing machine has two operating points that washing mode at constant torque point and dehydrating mode at high-speed point.Conclusion:For improvement of higher power density, 2-D finite elements analysis was performed to optimize the parameters of the shape of slit and notch to increase the torque. The torque increases by optimizing width and length of slit shape and notch shape. Finally, with the optimized parameters of shape of slit and notch, stack length was adjusted as per torque requirement for a washing machine motor and power density increases considering the safe factor from stiffness analysis.
