Abstract

This paper is about to discuss the effect of combining a magnetic shaping technique with an axial channel in the rotor core to reduce the cogging torque of a permanent magnet synchronous generator. Computation process is performed by using the optimization response surface method. In this case, this research is done by employing two types of axial channel systems, namely circular and hexagonal. The axial channel area at the core of the engine rotor is 0.000279683 m2. Determination of magnetic shaping was carried out with an angle of 10 and a surface angle of 530. The effect of the combination of the cogging torque reduction technique with magnetic shaping and axal channel was analyzed by numerical method based on the finite element method (FEMM). Based on the analysis, it is found that the combination shows a decrease in cogging torque by 98% when compared with the cogging torque in the initial design (initial structure). Another advantage of the combination of the two cogging torque reduction techniques is that there is no significant increase in the magnetic flux density of the engine core. It can be said that the combination of the cogging torque reduction technique and the axial channel at the core of the engine rotor can significantly reduce the cogging torque.

Abstract

This paper discusses the control of a stepper motor using Pulse Width Modulation (PWM) methods. In this paper, the author presents two designs: one using a stepper motor controller with an astable multivibrator as a pulse generator and the other utilizing a microcontroller as the pulse generator. The design of the stepper motor controller with an astable multivibrator involves using the IC timer 555 to control the stepper motor speed and a latch circuit to control the direction of the stepper motor rotation. Meanwhile, the design of the stepper motor controller with a microcontroller employs the Arduino UNO R3 to control both the direction and speed of the stepper motor. Testing is conducted through a simulation of the system design using Proteus software. From the test results, it is observed that an increase in the PWM value leads to a faster rotation speed of the stepper motor, conversely, a decrease in PWM value results in a slower rotation speed of the stepper motor.

Abstract

The purpose of research on this flood prevention system prototype design is to prevent flood caused by overflowing reservoir water. This system prototype uses the Modicon M340 Programmable Logic Controller as a controller and is equipped with a Human Machine Interface feature as a medium for managing and monitoring system performance virtually. This system is supported by a Water-Level Sensor to measure the water level in the reservoir and also the rate of addition of water in the reservoir. The sluice mechanism is driven by a Stepper Motor assisted by the ULN2003 Driver Module based on Proportional, Integral and Derivative (PID) control to maintain the water level in the reservoir. PID control in this system successfully runs optimally at constant KP = 3.5, KI = 2, and KD = 1, with an error result of 0,048%. This constant has the best response time compared to other constants, where rise time = 11.76 s, settling time = 13.95 s, and steady state time = 14.07 s.

Abstract

This research aims to compare the actual production with the simulations using the PVSyst software for the Off-Grid Solar Power Plant (PLTS) in Karuni Village, Southwest Sumba. The Off-Grid PLTS in Karuni Village is a vital solution for improving remote areas' electricity access. Actual energy production data from the PLTS were obtained from monitoring systems, while simulation results were obtained through PVSyst. The analysis results indicate a difference of approximately 10% between the actual and simulated results. It observed that it is influenced by variability in local weather conditions, maintenance, system management levels, and limitations of the simulation model. The implications of this research emphasize the importance of using accurate data in simulations, improving PLTS system maintenance, and developing more sophisticated simulation models. Recommendations for further research include further analysis of factors influencing the differences in results. This study provides valuable insights into the planning and management of Off-Grid PLTS. It offers perspectives on enhancing the accuracy of future PLTS system planning and management.

Abstract

ABSTRAKTorsi cogging adalah torsi yang terjadi akibat interaksi antara gaya tangensial di ujung magnet dengan material alur stator, yang menahan gerakan rotor pada generator magnet permanen. Torsi ini harus diminimalkan dalam aplikasi turbin angin karena dapat menghambat pergerakan awal generator. Penelitian ini bertujuan untuk menganalisis pengaruh metode tertentu dalam mengurangi torsi cogging dan pergeseran poros. Metode yang digunakan melibatkan penerapan coakan dua tingkat pada ujung magnet rotor dengan tiga konstruksi magnet rotor yang berbeda, sementara kondisi inti stator tetap identik. Analisis numerik menggunakan FEMM 4.2 menunjukkan pengurangan torsi cogging yang signifikan sebesar 99,70% dan pengurangan pergeseran poros sebesar 60% secara vertikal dan 51% secara horizontal.Kata kunci: coakan dua tingkat, generator magnet permanen, gaya magnet tangensial, torka cogging, pergeseran poros ABSTRACTCogging torque is the torque resulting from the interaction between tangential forces at the magnet's edge and the stator slot material, which opposes the rotor's motion in a permanent magnet generator. This torque must be minimized in wind turbine applications as it can hinder the generator's initial movement. This study aims to analyze the effect of a specific method on reducing cogging torque and shaft shifting. The method involves applying a two-step notch at the rotor magnet's edge with three different rotor magnet constructions, while keeping the stator core conditions identical. Numerical analysis using FEMM 4.2 achieved a significant cogging torque reduction of 99.70% and reduced shaft displacement by 60% vertically and 51% horizontally.Keywords: Two-step notch, permanent magnet generator, tangential magnetic force, shaft shifting
