Finite element method became an indispensable tool for engineers working in various industrial areas. The foundation of this development is the assumption that the model reflects with known accuracy the real system. In case of modal analysis, the number of uncertainties due to the simplification of the system, accuracy of the finite element method and nonlinearities of the system revealed by testing methods are overlapping and making the validation of the model challenging. The aim of this paper is to study the vibration behavior of an axial-flux permanent-magnet motor used as hoisting machinery for elevators. After assessing the uncertainties, both in modeling and testing, the motor is analyzed starting with each component and build up sequentially until the final assembly. A special attention is paid to the modeling choice of bearings. As a result, the status of the validation is assessed and the future development planned.
