Abstract :
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%.
