STUDI SIMULASI INVERTER DRIVE UNTUK APLIKASI LIFT

The development of automation technology in industry grew rapidly expand along with the progress of time. Earlier in the electric motor speed settings for applications lift /
elevator only use a manual speed control, played a pulley size, or gearbox. However, at this time, is already available control device that can control the speed of motors AC 3 Phase, the inverter drive. Inverter drive is able to adjust the speed by changing the frequency and
voltage values on 3 phase AC motor, inverter drive also has advantages as soft starting, braking 3-phase AC motor, the system also behind a 3 phase AC motor rotation.
In this test, the slip speed between rotor stator with the smallest of 35% occurred at a frequency of 4.4 Hz value with 2397.2 grams load when the elevator moves up, while the
biggest slip amounting to 67% where the value of the frequency of 2.5 Hz with a load of 1549, 8 grams when the elevator moves up. Slip smallest valued at 1,125 Hz frequency with a frequency value of 2.5 Hz with a load of 700 grams when the elevator down, while the biggest slip worth 3.21 Hz frequency with a frequency of 4.4 Hz with a value of 2397.2 grams load when the elevator moves up.
