An induction motor is a key device for an industrial machine. The installation misalignment of the motor will result in derating problems and energy consumption that is generally used to analyze signal faults using the fast Fourier transform (FFT) method. Problems with the rotor affect the non-stationary signal and FFT can be utilized to analyze this problem inefficiently. This paper proposed the testing and analysis of faults in an eccentric rotor at different levels using the stator current detection technique and the calculation of the energy signal coefficient via the wavelet decomposition (WD) method. The experimental results showed that an increase in eccentricity had a linear relation with the energy signal, where R2 was 80.81%. Moreover, the test results illustrated that the proposed method was more efficient than FFT and applicable to motor fault analysis and application in the industrial.

Development small and medium enterprise (SME) of Thailand have been important for generating incomes and developing community-based business of Thai people. This paper proposes a development efficiency of machetes production in the Ban Na Thon community of Nakhon Phanom province. This strategy is apply by the industrial cluster method and development an innovation. The methodology consisted of 4 steps. The first study involved a study context of community, coordination with people, meetings and recording primary data with interviews and questionnaires. The research participants were people in the community in Nakhon Phanom University. The performance of the proposed development and design furnace can be controlled by proportional integral derivative (PID) at the temperatures ranging from 0 to 1,200 °C; the development the hardening tub can be controlled by the temperature of water in the hardening process, development of grinding machine. Results confirm that this development research has an efficiency more than conventional method.
