| dc.description.abstract | The increase in the use of conventional motor
causes an increase in the use of petroleum that cannot be
renewed. To overcome it the use of conventional motor
changes to electric motor. Electric motor that are often
used is brush motor, but it has brush-loss. Electric motor
created to overcome the weakness of brush motor. Electric
motor that are designed has specification ie 6 slot and use
4 dan 8 magnet in rotor. The coil in every slot is 450 made
by email wire with 0,3 mm diameter.
This research is doing by measurement and
calculation. Measurement is included measure magnetic
field, motor voltage, frekuensi and rotational speed.
Calculation is included power, torque, frekuensi and
rotational speed. Motor testing is using 4 and 8 magnet in
no load condition and with load condition. The first test on
a 24 Volt supply voltage when using 4 magnets in no-load
condition result a torque value of , ૢ࢞ିNm and a
speed of 2794 RPM, when in load condition motor result
torque value of , ࢞ ିNm and rotational speed of
1171 RPM. The second test on a 24 volt supply voltage
when using 8 magnet in no-load condition motor result
torque value of , ૡ࢞ ିNm and rotational speed of
1410 RPM, when in load condition motor result torque of
ૠ, ࢞ ିNm and rotational speed 1410 RPM. Maximal
value torque result in all test is ૠ, ࢞ ିNm and
maximal rotational speed is 2794 RPM | en_US |
