Abstract

This research is motivated by the many needs in the use of electric motors. Electric motors with DC voltages that are often used today are less effective and efficient because of the use of brushes that will run out when used. To overcome the weaknesses of this DC motor, then used Brushless Direct current Motor (MASTS). MASTS is a three phase AC motor. In a fixed application, a three phase AC voltage source can be used directly. In a mobile application, it takes an AC voltage sourced from a DC voltage. For this reason, an inverter is designed to convert DC voltage into three phase AC. The method in controlling MASTS is a six-step inverter that is changing the DC voltage to AC voltage in the form of a box or trapezoid. This inverter uses MOSFET IRF3205 and Arduino microcontroller. To find out the performance of the inverter, MOSFET driver voltage measurements, measurement of the output current, and measurement of the resulting MASTS speed. From the measurement results, when the voltage is increased the current in the circuit and the speed of the MASTS will increase. Keywords: Inverter, MASTS, Phase, Six-Step.

Abstract

This study aims to create a PWM inverter that can drive the Brushless Unidirectional Flow Machine (MASTS). PWM inverters are intended to correct deficiencies in six-step inverters. Inverter is a circuit that is used to convert a DC voltage source into an AC voltage with a certain frequency. The use of inverters is found in electric vehicles. The system often used to control an inverter is a Pulse Width Modulation (PWM) based control, where pulse width is used to regulate speed. The inverter is tested using 3 pairs of mosfets as a switch to control the three-phase output of the inverter. In the inverter, PWM is used to adjust the width of the frequency pulse that will be given to the mosfet. This research used 3 variations of duty cycle 30%, 60%, 90% to determine the effect of MASTS speed on PWM by using a PWM inverter. The results of this study the speed of MASTS can be influenced by changes in duty cycle, with increasing value of the duty cycle, the faster the speed of MASTS, and vice versa. Keywords:Mosfet, Sensor Hall, MASTS, PWM, Inverter.

This research aimed to see whether there is a difference between learning outcomes using cooperative learning model Teams Games Tournament ( TGT ) with the learning outcomes using direct learning. This research is an experimental research, the researchpopulation is a class X student of the installation of Electric Power Engineering SMK Negeri 1 Tanjung Raya TA 2013/2014 . The sampling technique was done by using nonprobability sampling with purposive sampling . The data collected from the test results in the form of learning objective questions about as many as 35 points . Data were analyzed using Microsoft Excel to test homogeneity , normality , and hypothesis testing . From the results of research conducted tests on samples of both groups gained an average of learning outcomes for the experimental group the average value of the initial test was 49.1 and the average value of the final test is 81.8 with an increase of 32.7. For the control group the average value of the initial test was 52.2 and the average value of the final test is 72.2 with an increase of 20 . The results of the hypothesis by using Microsoft Excel found that tcount 5,960 > 1,671 ttable, so the alternative hypothesis (H1) is accepted or rejected the null hypothesis (H0). This means that the average significant learning outcomes experimental class higher than the average of the control class learning outcomes .

Abstract

The use of Brushless Direct Current Machines (MASTS) is very much applied in the industrial world compared to other types of drive engines. For the MASTS drive a three-phase inverter is needed, a three-phase inverter is a circuit that is used to convert DC voltage into AC voltage with a certain frequency. The system used to control the inverter is to use Pulse Width Modulation (PWM), where the pulse width is used to regulate the speed. To optimize the MASTS rotation speed, it is necessary to make speed monitoring to determine the stability of the MASTS speed, so design is carried out by combining the monitoring of the MASTS speed with a three-phase inverter. This tool uses a hall sensor, Arduino, and liquid crystal display (LCD) display. The working principle of the hall sensor is detecting the rotation speed of the MASTS based on the working principle of the electromagnetic hall sensor. In this study, 5 variations of PWM potentiometer inputs 20%, 40%, 60%, 80%, 100% were used to determine the results of monitoring of the MASTS speed for each input variation. In this study, an error rate of 6.2% was observed.. Keywords: Sensor Hall, SMATS, Inverter, RPM

Abstract

Instructive frameworks normally utilize old-style strategies for execution assessment. In this framework, understudy execution relies upon Quiz outcomes and is assessed uniquely as progress or disappointment. Elective, non-traditional execution assessment strategies might be utilized, like fuzzy rationale, a numerical procedure of set-hypothesis that can be applied to many types of dynamic remembering research for designing and man-made brainpower. This review proposes another presentation assessment technique dependent on fuzzy rationale frameworks. Understudy execution of Control Technique Laboratory in University State of Padang Technical Education Faculty, electronics engineering Department, was done with fuzzy rationale and it was contrasted and old-style assessing strategy. Study Quizs are notes in which twenty understudies took the control procedure lab course. Assessment of the outcomes showed varieties among the traditional and fuzzy rationale techniques. In spite of the fact that exhibition assessment utilizing fuzzy rationale is confounded and requires extra programming, it gives some assessment benefits. fuzzy rationale assessment is adaptable and gives numerous assessment alternatives, while the old-style strategy holds fast to consistent numerical estimation. At the implementation stage, the instructor liable for the lab implementation can alter the scopes of participation capacities and rules, allowing non-homogenous yet adaptable and target execution assessment.
