The substructure synthesis method using the experimental and the finite element techniques is applied to a compact motor used as a part of vacuum cleaner. Since a compact motor is so complicated in its geometry, it is difficult for the computation load to analyze the vibration of the whole structure at the time. Therefore, the mode synthesis method using the experimental and analytical data is applied to the motor. It is divided into substructures, as a rotor, a stator and two frames. The transfer function for each substructure is measured by impact testing, and those modal parameters are extracted by the curve fitting procedure. However, the modal parameters of the rotor are obtained by the formulation of FEM, because it has a few measuring or exciting points. The modal characteristic obtained from the all substructures is synthesized by using the mode synthesis method, and the dynamic characteristic of the whole structure is analyzed.
