Abstract

The vibration and noise of the motor is a significant factor to evaluate the quality of the motor and the modal analysis is one of the main approaches to study the structural dynamic characteristics of motor. The motor will be in the resonance state when the excitation frequency of the harmonic electromagnetic force is close or consistent to the natural frequency of the motor, thus produce vibration and noise with high amplitude. Aim at the modal analysis problem of motor, firstly the three-dimensional (3-D) whole induction motor model including components, e.g., stator, frame, cover, is elaborately established using Pro/Engineer software; then the model problem of motor is simulated and analyzed based on finite element method (FEM), and compute and analyze the relevant components for the effect; of motor structural modal respectively; finally, compare the computation results with the experimental ones to verify the correctness of the proposed approach through the hammering method test. Through the computation and analysis of the motor model in this paper, some basis references and foundation have been established for the design and further research of motor.
