Model simulation and experimental work are carried out on a simplified motor structure using Statistical Energy Analysis(SEA). Comparison between FE/SEA hybrid model built by VA One, FE simulation using independent random excitation and experiments validates the feasibility and accuracy of the hybrid modeling method using VA One for motor structural high-frequency vibration. This research expands the application of SEA in motors.
