Along with the development of the industrial sector, companies are competing to create quality and affordable products. To support production, automation tools have emerged that help the production process so that it is faster. One of the machines that is widely used by large factories is a 3-phase induction motor. 3-phase induction motors are often used in driving equipment in industry because they have a simple construction, are relatively cheap, lightweight, have high efficiency, and are easy to maintain. This study utilizes the A3114 hall effect sensor device, PZEM-PP4T Sensor, 20x4 LCD, ESP32 module, Relay, Mitsubishi D700, MCP 4725 Sensor. The tests carried out showed that the performance of the sensor for measuring speed, voltage, and current on 3-phase motors has a high level of accuracy. Testing of motor speed shows a difference in speed value (Rpm) between the hall effect sensor and the tachometer, with an average accuracy percentage of 4,12%, indicating that the hall effect sensor has a fairly good level of accuracy. For voltage measurement, the Pzem sensor compared to the Multitester produces an average accuracy percentage of 0,90%, indicating that the pzem sensor is very reliable. Meanwhile, current testing shows a difference in value between the pzem sensor and the multitester with an average accuracy percentage of 0,98%, indicating a fairly high level of accuracy. Overall, this system can be relied on for measuring operational parameters of 3-phase motors because it has consistent and good accuracy. With this research, the 3-phase induction motor monitoring system which was originally done manually has changed to automatic and has a fairly high level of work efficiency.

This study aims to examine the impact of a 6-phase design using an asymmetrical dual 3-phase design on the torque and speed of an induction motor, where the newly designed motor still uses a 3-phase power source. The research compares the performance of a conventional 3-phase induction motor with that of an asymmetrical 6-phase induction motor design, focusing on torque and speed. This motor is only designed in terms of its windings, so the motor's position remains unchanged. The 3-phase system applied to the 6-phase induction motor design ensures that the 6-phase motor operates within a 3-phase system. The study also explores performance improvements, particularly in torque and speed, by redesigning the windings of a 3-phase induction motor into an asymmetrical 6-phase motor. The induction motor used in this research has the following specifications: 3-phase, 2 A, 1390 RPM, 50Hz, 0.75 kW, and 380Y. The study aims to understand the effects of the asymmetrical 6-phase induction motor design, particularly regarding torque and speed. The results show that the torque and speed of the two motors differ due to the asymmetrical 6-phase winding design. In a conventional 3-phase induction motor, the winding coil layer distance is 120°, whereas, in the asymmetrical 6-phase induction motor, the distance between the first and second layers is 30°. Based on this analysis, the asymmetrical 6-phase induction motor design demonstrates better performance compared to the conventional 3-phase induction motor.

The frequency setting is VSD (variable speed drive) or inverter. In controlling the speed of a 3-phase induction motor using a VSD or inverter, the PWM (pulse width modulation) method is used. PWM is a method of manipulating the signal width, which is described by pulses in one period. In collecting data, the methods used are observation, interviews, documentation, and literature studies. The data obtained in the observation are the values of frequency, voltage, and current at the output of the VSD, which goes to the source of the 3-phase induction motor. The results obtained from setting the motor speed by setting the frequency at 25 Hz are 1500 rpm, 30 Hz is 1800 rpm, 35 Hz is 2100 rpm, 39.1 Hz is 2346 rpm, and 40 Hz is 2400 rpm. By adjusting the input frequency to a 3-phase induction motor using a VSD or inverter, it can be concluded that the higher the frequency, the faster the rotation speed of the pump motor, and the resulting water discharge in sucking water will also be greater.

PT. Sejin Lestari Furniture is a company engaged in the production of furniture such as doors, tables, chairs, cabinets, bookcases and other interior equipment. As one of the companies that have succeeded in producing finished goods in large quantities, PT. Sejin Lestari Furniture relies on the help of an electric motor at every stage of its production, including one of the wood pellet production machines, namely the biofuel pelletizer molding machine which has four different types of motors. In order to work optimally, electric motors need a protection system that can protect them from threats. In this study, the protection system used is Thermal Overload Relay (TOR) which functions as an overload controller so that the electric motor is not easily burned or damaged. In this case, the TOR must be adjusted according to the capacity of each induction motor so that when an overload occurs, the TOR will automatically cut off the current flowing in the motor so that damage can be avoided. The TOR trip standards in this study uses the NEMA (National Electrical Manufactures Association) standard with the method used, namely Research and Development (R&D) where this method is carried out to produce certain products and test the effectiveness of these products. The data collection was obtained through journals and books.

Penggunaan motor listrik dengan kontaktor sebagai pengendalinya dapat menyebabkan arus (starting) motor melonjak saat start pertama dihidupkan. Dalam perkembangan teknologi, Variable Speed Drive (inverter) berfungsi untuk mengurangi konsumsi energi listrik dalam mengendalikan kecepatan putar motor listrik dengan mengubah prinsip frekuensi inputnya, sehingga dapat memungkinkan upaya penghematan konsumsi energi dan peningkatan produksi terhadap kapasitas pabrik. Penggunaan motor listrik yang fungsinya sebagai penggerak mesin merupakan contoh penggunaan motor listrik yang tidak efisien dan membutuhkan energi yang cukup besar, Selain itu, penggunaan motor listrik masih menggunakan cara tradisional, yaitu dengan mengguakan kontaktor. penggunaan kontaktor dapat menyebabkan arus (starting) motor melonjak saat start pertama dihidupkan. Lonjakan arus start yang cukup besar ini juga berdampak pada pemborosan konsumsi daya. Namun, lonjakan ini dapat di minimalkan dengan memodifikasi teknik pengendaliannya yaitu menggunakan VFD. VFD dapat mengatur lonjakan arus startin sesuai dengan kebutuhan yang diperlukan, yaitu dengan cara mengubabh frekuensinya.

Salah satu cara paling umum untuk mengontrol kecepatan adalah dengan menggunakan sensor enkoder Data yang dihasilkan akan ditampilkan di komputer atau laptop Anda. Saya tahu pengamatan mereka. Semakin banyak motor memiliki biaya perawatan yang lebih rendah selain efisiensi, torsi, kecepatan dan variabilitas. motor DC ini memiliki proses pergantian yang lebih cepat dan biaya perawatan yang lebih rendah, yang menyebabkan sikat menjadi percikan api dan cepat menjadi rusak. Rotor terbuat dari kumparan dan diinduksi oleh medan magnet berputar stator, yang menyebabkan arus listrik di rotor. Kecepatan putaran rotor jauh lebih lambat daripada kecepatan putaran medan magnet stator. Akibatnya motor induksi cenderung kurang efisien dibandingkan motor DC kecepatan tinggi, bisa fluktuatif, dan biaya perawatannya lebih rendah, sehingga digunakan motor DC brushless atau biasa dikenal dengan motor BLDC.

Permasalahan kelistrikan yang sering terjadi pada motor induksi ialah tidak seimbangnya tegangan phasa yang menyebabkan kinerja motor induksi yang semakin berkurang. Ini ditandai dengan adanya kenaikan temperature yang menyebabkan umur motor induksi tersebut berkurang.
