Vibration analysis based on magnetic field balancing technique

Abstract

This paper presents the design of a vibration measurement system according to ISO 10816-1 standard. In this study, a vibration measuring device was applied the magnetic field balancing technique. For study, the vibration generated for experiment was from a vibration of the motor which taking load in various conditions. The operation and performance analysis of the motor in terms of balance and unbalance position of load can be determined by dividing the experiment into four conditions: Balance position, 25% of unbalance position, 50% of unbalance position and 75% of unbalance position. The magnetic field method influenced by the permanent magnets was applied and the Hall Effect sensor was used as a sensor. The results of the experiment were then compared to those from output voltage of the Hall Effect sensor as well as those from the magnetic field density for analysis the vibration and the effectiveness of motor. The results of the experiment can be considered in terms of torque, frequency and the output voltage of Hall Effect sensor. It was found that the output voltage of Hall Effect sensor at balance position, 25% of unbalance position, 50% of unbalance position and 75% of unbalance position were equal to 2.54 V, 2.67 V, 2.77 V and 2.86 V, respectively while the average of process error was 0.34%.
