Abstract

Electrical energy is the main energy for humans. Electrical energy has a very important role in the development of modern technology in all sectors of households and industries. Electrical energy must be sustainable for human survival. Therefore, the problem of saving electrical power needs to be raised in research. This study aims to design a solar panel-based power bank to meet household electricity needs such as fans. This is done to reduce the use of electricity costs sourced from PLN. The study's results showed that by using 1 sheet of GH Solar 50 Wp solar panel, 4 units of LI-P0 12 Volt 22 AH batteries using a series circuit and an inverter. Each installed component meets the specifications, so this PLTS system can turn on 1 fan unit with a load power of 42.0 Watts. Furthermore, for charging HP of 8 watts and Laptop of 40.3 watts for 2 hours 45 minutes for 1 day.

Abstract

In the industrial world, the motor winding process is one of the important stages in the manufacture and rewinding of electric motors. Many electric motors are damaged and even the motor can burn because in the operation of electric motors often serve loads that exceed the limits of the motor's ability (overload), contaminated with foreign objects, age, bearing problems, which can cause the effect of changing the current, causing heat which if left for a long time can cause burning of the motor wire winding. With the damage to the motor wire winding, a cost-effective solution that can be done is to rewind the motor wire. the motor rewinding process is carried out so that the winding can return to normal and work properly. The research was conducted using the experimental method. In the research, an automatic rolling device using an Arduino microcontroller was designed. The test results that the system can function normally in the process of inputting the value of the number of rolls, rolling driven by stepper motors and LCD has functioned properly in displaying each data on the system designed.
