Dalam penelitian ini telah dianalisis efek air gap terhadap performa generator listrik tipe fluks aksial berbasis magnet permanen NdFeB. Analisis performa dilakukan dengan mengukur output tegangan generator listrik fluks aksial terhadap ukuran air gap dan kecepatan putar rotor. Air gap antara stator dan rotor divariasikan dari 7 sampai 20 mm. Dari hasil eksperimen, peningkatan remanansi magnet berbanding lurus terhadap peningkatan output tegangan. Sebaliknya, peningkatan ukuran air gap menurunkan tegangan output secara linier. Hal ini disebabkan oleh adanya penurunan magnetik flux density secara exponensial. Pada ukuran air gap 7 mm dan kecepatan rotor 1500 rpm, dihasilkan output tegangan maksimal untuk Br = 0,2 dan 1,3 Tesla berturut-turut sebesar 10,4 dan 67,7 volt.
