| dc.description.abstract | Technology that is growing rapidly and
innovations that have sprung up in the electrical field today
are driving the use of electricity as a source of energy to do
work. Electric motor is one component that is very popular
in the industrial world and households that are useful to
human life. In addition to DC motors and induction motors,
there are also 3 phase brushless direct current (BLDC)
motors which are a type of synchronous motor where
magnetic fields are produced by rotor and stator at the same
frequency. The rotor is a moving part of the brushless direct
current motor which is a place of permanent magnet called
a pole. This paper discusses the performance of brushless
direct current 3 phase axial flux motors with different
diameters of neodymium type permanent magnets. Tests
carried out using neodymium permanent magnets with
diameters of 15mm x 2mm and 20mm x 2mm were tested
without using a load and using load. The parameters used in
testing motor performance include speed, torque, and motor
power with a source voltage of 12V, 16V, 20V, and 24V. The
test results shows that the speed value of a BLDC motor
using permanent magnets with a size of 20mm x 2mm is
greater than that of permanent magnets of 15mm x 2mm.
The same thing applies to the value of the power produced
while, for the value of torque when the motor uses a
permanent magnet of 15mm x 2mm will be greater than that
of a motor using a permanent magnet of 20mm x 2mm. | en_US |
