Abstract

Many types of equipment today are required in service well for 24 hours a day and beyond their intended lifetimes. Then, to dismantle them for inspection from time to time is very expensive while the owners need to consider all the faults before making the decision. Therefore, vibration signature is introduced to help the owners to decidebased on all the relevant information taken. Vibration signature is an essential tool to detect motor problems, which can identify the specific faults like bearing or gears, or rotor imbalances without interrupting the operation of the motor. The techniques used in the vibration signature are field measurement with portable instruments, field recording followed by detailed analysis and permanent online monitoring. Each iibration shows the different characteristic that determined by the running speed, the number of poles on the rotor, the numbers of slot in the rotor or statof, and other variables. The objective of this project is to identify most of the bearing defects during the operation and provide valnable information to develop a maintenance schedule before the motor breaks down. All in all, from all the infermation, the owner can reduce the amount of unscheduled downtime while extend the running time of the motor ana also decrease ebe energy costs.
