Introduction

Rancang bangun trainer pengendali kecepatan motor induksi 3 fasa menggunakan variable frequency drive (vfd) fr-d700. Rancang bangun trainer pengendali kecepatan motor induksi 3 fasa menggunakan Variable Frequency Drive (VFD) Mitsubishi FR-D700. Pelajari pengaturan kecepatan motor.

Abstract

Pengaturan kecepatan motor induksi tiga fasa pada dasarnya dapat dilakukan dengan mengubah jumlah kutub motor atau mengubah frekuensi suplai motor. Pengaturan kecepatan dengan mengubah jumlah kutub sangat sulit karena dilakukan dengan mengubah kontruksi fisik motor tapi dengan megubah frekuensi suplai motor akan jauh lebih mudah dan tidak terbatas tampa harus merubah konstruksi fisik motor. Variable Frequency Drive (VFD) atau sering disebut inverter merupakan suatu alat yang digunakan untuk mengendalikan kecepatan putaran sebuah motor yang dapat disesuaikan dengan kebutuhan, pada trainer ini inverter yang digunakan Mitsubishi Electric seri FR-D700 – 1,5 kW. Untuk mengoprasikan Variable Frekuency Drive (VFD) harus melakukan setting parameter terlebih dahulu. Hal ini dilakukan agar dapat menghasilkan frekuensi yang bervariasi sehingga kecepatan putaran motor berubah-ubah sesuai dengan frekuensi yang diterimah. Berdasarkan pengujian yang dilakukan dengan frekuensi berbeda-beda dalam range 5–50 Hz. Parameter pengujian berupa pengukuran tegangan, pengukuran arus, dan keceptan putar rotor. Berdasarkan hasil pengujian yang telah dilakukan, diketahui bahwa pemasangan VFD pada motor memiliki kemanpuan untuk mengatur kecepatan dengan baik.

Review

This paper, titled "Rancang Bangun Trainer Pengendali Kecepatan Motor Induksi 3 Fasa Menggunakan Variable Frequency Drive (VFD) FR-D700," addresses the practical design and implementation of a training module for three-phase induction motor speed control. The work focuses on utilizing a Variable Frequency Drive (VFD) as a modern and efficient method for adjusting motor speed, an approach highly relevant for educational and industrial applications. The authors correctly highlight the advantages of frequency control over traditional pole-changing methods, establishing a clear motivation for their project. The choice of the Mitsubishi Electric FR-D700 – 1.5 kW VFD provides a specific and common industrial component, making the trainer highly practical and relatable for students and practitioners. A key strength of this work lies in its hands-on approach to demonstrating a fundamental concept in electrical machine control. The abstract clearly outlines the methodology, including the necessary parameter setting for the VFD and the experimental range of 5-50 Hz for frequency variation. The chosen test parameters—measurement of voltage, current, and rotor speed—are appropriate for characterizing the VFD's performance in controlling the motor. The reported finding that the VFD successfully regulates motor speed is a positive indication of the trainer's functionality and its potential effectiveness as an educational tool for illustrating the relationship between supply frequency and motor speed. While the abstract provides a concise overview, the full paper would benefit from a more detailed elaboration on several aspects. For instance, a deeper discussion on the specific design and construction of the "trainer" aspect, beyond just incorporating the VFD, would enhance its contribution. Furthermore, presenting specific quantitative results (e.g., graphs of speed vs. frequency, or efficiency at different operating points) and a more rigorous analysis of the observed relationships between frequency, voltage, current, and rotor speed would significantly strengthen the empirical evidence. Exploring the pedagogical implications of the trainer and potential exercises or learning objectives it aims to fulfill would also add value. Overall, this paper presents a sound foundation for a practical educational tool in motor control.
