This study is conducted to build magnetic generator to produce magnetic field with which the effect of the changing magnetic optic caused by the generated magnetic field on a sample between the two groups of coil could be quantitatively studied. The uniformity of the magnetic field between the two groups in three dimension also examined. The magnetic generator is consisted of auxiliary coil, which is reversed for each groups, that is integrated with a ferromagnetic material as the core to amplify the magnetic induction. The current supplied to the system is up to 10 A and generate up to 0,1 T which can be controlled via microcontroller computer communication protocol. The developed magnetic generator will be used in another study to generate magnetic field for faraday rotation instrumentation. This study produced a transfer function B vs. I is B 98,26502i 18,27325."

"Generator Sinkron Magnet Permanen Fluks Aksial Tanpa Inti Stator memiliki unjuk kerja yang pada umumnya ditentukan oleh gelombang tegangan dan arus. Kedua hal tersebut dipengaruhi oleh konfigurasi Desain geometris generator. Studi ini membandingkan pengaruh jumlah kumparan stator terhadap nilai dan bentuk gelombang fluks magnet dan tegangan keluaran. Asumsi jumlah kutub magnet rotor pada tiap Desain penelitian adalah sama yaitu 24 kutub. Kesimetrisan antara setiap permukaan stator yang menangkap fluks magnet dari rotor setiap waktu sangat mempengaruhi tegangan keluaran. Hasil studi menunjukkan bahwa Desain 9 stator sesuai untuk konfigurasi tiga fasa sedangkan Desain 12 stator selaras untuk generator konfigurasi satu fasa.

A Coreless Axial Flux Permanent Magnet (AFPM) Synchronous Generator has a work quality that is determined by the voltage and current waves. Both of those things are influenced by geometric configuration of the generator. This research compares the effect of the number of stator coils to the magnet flux captured and the voltage generated for every design. It is stated that the number of rotor magnetic poles in every design are same, 24 poles. How symmetrical between every stator`s surface capture the magnetic flux in every second is very extremely affecting the output voltage. The result of this research proves that design with 9 coils is appropriate for three phase configuration, while design with 12 coils is suitable for one phase configuration of generator."

"This study reports a novel strategy for minimizing torque ripple in a radial flux inset permanent magnet (RFIPM) generator by using a geometric modification of the magnet poles. We simulate the design of three different types of edge-rounded magnet (ERM) poles using finite element method magnetics (FEMM) software for a 16 poles and 24 slots RFIPM generator. We found that the edge-rounding of magnet poles significantly lowered the torque ripple of the generator with a reduction of about 74% (torque ripple of 7.76%). In addition, the modified RFIPM generator exhibited enhanced flux density uniformity in the air-gap of the generator (up to ~ 48.8%), leading to a smoother line of flux density."
