Abstract

Dalam pengoperasian motor induksi 3 fasa, ada dua hal yang menjadi permasalahan yaitu arus starting yang besar dan kesulitan mengatur kecepatan putar pada motor. Arus starting yang besar dapat dikurangi menggunakan beberapa metode starting, seperti metode tahanan depan, metode Y Δ, metode autotransformer dan metode softstarter. Dengan berkembangnya teknologi hal untuk mengatur kecepatan motor menjadi permasalahan yang mudah dilakukan dengan menggunakan komponen Variabel Frequensi Drive VFD. Pengaturan frekuensi menggunakan Variabel Frequency Driver VFD menggunakan signal 4mA sampai 20mA sehingga kecapatan putar motor dapat variasikan sesuai dengan setting tersebut, alat ini akan di pasang pada mesin Sawmill pemotong kayu sengon CV. Wana Indo Raya Lumajang, Jawa Timur. Setelah melakukan pemasangan alat Variabel Frequency Driver VFD dan melakukan perbandingan data menggunakan dan tanpa VFD. Dimana hasil perbandingan pengukuran data arus, daya, dan kecepatan starting motor tanpa beban lebih baik menggunakan VFD. Nilai arus starting hubung star tanpa VFD dengan waktu 3 detik sampai 15 detik dengan nilai 47A sampai 27,3A dan hubung delta tanpa VFD dengan 34,5 A sampai 8,4A . Menggunakan VFD mulai 0Hz sampai 50Hz dengan nilai arus 6,5A sampai 6,1A. Kemudian untuk pengaturan kecepatan motor saat dibebani kayu dengan ketebalan13, 22, dan 30 cm mendapat kan nilai set frekuensi 50Hz, 52Hz, dan 53Hz untuk mencapai kecepatan 2945 RPM saat memotong kayu log dengan ketebalan berbeda.
