Utilization of renewable energy, such as water and wind always has constraints in the form of varying and not constant water or airflow velocity so that a generator is capable of working in that condition. This study aims to design a permanent magnet generator with a size calculated based on a target output power of 500 watts. The dimensions of the generator produced are calculated by the equation and produce a rotor diameter and core length of 108 mm and 52 mm. The generator is designed to have 18 slots, 16 poles and 3 phases. The generator is tested with different speed variations and no load. No-load test results with variations in the speed of 50 rpm, 250 rpm, 500 rpm, and 1000 rpm produces a voltage of 11.30 volts, 56.52 volts, 113.04 volts, 169.53 volts, and 226.08 volts. After that, the generator is tested with load variations 5 Ω, 10 Ω, 15 Ω, and 20 Ω in order to get the value of its power and efficiency. The highest power produced at a speed of 500 rpm is 580,791 watts. The highest power produced by the generator is at a speed of 1000 rpm which is 1170.53 watts. the highest efficiency produced by this permanent magnet generator is 79.76%.
