【 摘 要 】

Characteristics of magnetic-gear axial using 4 rectangular NdFeB magnetic layers mounted on acrylic disks have been studied experimentally. The goal is to reduce the use of NdFeB magnets to be more economical compared to other magnetic gear designs. The magnetic gear axial topology made was different from the magnetic gear that had been made by the previous researchers. The method used is to conduct experiments by taking comparative data between motors that are directly coupled to the generator with that using magnetic transmission gear. The results obtained show that using 4 layers of the rectangular magnet with a magnet of 258 mT can increase the magnetic torque of the gear. Comparison of torque obtained at 200 Ohm load for direct coupling is 0.19 (N-m), while for magnetic transmission gear is 0.18 (N-m).
