EXPERIMENTAL STUDY ON VIBRATION CHARACTERISTICS OF AN AC SYNCHRONOUS MOTOR AND THEIR ENVIRONMENTAL IMPACT

Abstract

Electric machinery serves as a fundamental driving force in various industrial production processes. The three-phase synchronous motor is the most widely recognized type of electric machinery used in industrial plants due to its robust structure, high power output, and ease of maintenance. However, unexpected motor failures can lead to production disruptions. Since one of the key factors contributing to motor failure is vibration, this article presents an analysis of the vibration characteristics of an AC motor and examines its environmental impact. Since moving machinery inherently generates vibrations, this study specifically investigates the vibrations occurring both at the motor itself and at its mounting base. These vibrations can significantly affect the surrounding physical environment, including the buildings and facilities where the motor is installed. Experimental comparisons of vibration levels reveal that the vibration characteristics of an AC motor vary at different positions, including drive end, non-drive end, and motor base. Measurements indicate that the non-drive end exhibits the highest vibration levels under all load conditions, since the rotor shaft extends the farthest from the stator at the non-drive end, leading to increased oscillations. In contrast, the motor base experiences the lowest vibration levels since it is not directly attached to the motor. The findings from this study will contribute to the development of predictive maintenance strategies. The failures are typically detected after they occur, resulting in repair delays, downtime, and production losses. Identifying potential motor failures in advance can reduce operational disruptions, minimize maintenance costs, and improve overall efficiency.
