Abstract

Technology that is growing rapidly and innovations that have sprung up in the electrical field today are driving the use of electricity as a source of energy to do work. Electric motor is one component that is very popular in the industrial world and households that are useful to human life. In addition to DC motors and induction motors, there are also 3 phase brushless direct current (BLDC) motors which are a type of synchronous motor where magnetic fields are produced by rotor and stator at the same frequency. The rotor is a moving part of the brushless direct current motor which is a place of permanent magnet called a pole. This paper discusses the performance of brushless direct current 3 phase axial flux motors with different diameters of neodymium type permanent magnets. Tests carried out using neodymium permanent magnets with diameters of 15mm x 2mm and 20mm x 2mm were tested without using a load and using load. The parameters used in testing motor performance include speed, torque, and motor power with a source voltage of 12V, 16V, 20V, and 24V. The test results shows that the speed value of a BLDC motor using permanent magnets with a size of 20mm x 2mm is greater than that of permanent magnets of 15mm x 2mm. The same thing applies to the value of the power produced while, for the value of torque when the motor uses a permanent magnet of 15mm x 2mm will be greater than that of a motor using a permanent magnet of 20mm x 2mm.

Abstract

This paper recounts design and development the realtime and wireless monitoring systems to observed the characteristics and performanced of the solar photovoltaic (pv) energy generation. The monitoring systems designed used the Raspberry Pi 3 as the data processing center, the voltage divider as the voltage sensor, ACS712 as the current sensor, DHT as the temperature sensor, and BH1750 as the solar irradiation sensor. The measurements of the pv generation characteristics are carried out all the time in real time. The monitoring systems developed has calibrated with standard measuring instruments. The measurement data has processed, sent and stored in the database via the internet. The MySQL database with single user interface using the Web-based programming language has employed. This research has proven that the system designed to functioning properly and correctly to achieve the objectived. The novelty of these project are the pv wireless monitoring systems techniques with the simple device resources, capable of showing maximum performanced.
