One of the types of generator is a permanent magnet generator which is an effective type of generator for use in low-speed power plants with the direction of flux used is axial flux. This study was conducted to examine the output voltage resulting from the rotational speed of the rotor which was varied with speeds of 200 rpm, 300 rpm, 400 rpm, 500 rpm, 600 rpm, 700 rpm, 1000 rpm, 1500 rpm, 2000…
