1D Modeling Considering Noise and Vibration of Vehicle Window Brushed DC Motor

Abstract

This study proposes 1D modeling that considers the noise and vibration of a vehicle window-brushed DC motor. The electrical and mechanical components of the brush DC motor are included, creating a model that considers noise and vibration. The model has a back electromagnetic force (EMF) including vibration components and is constructed based on an electric circuit and transfer functions. To ensure the reliability of the model, the back EMF, noise, and vibration experiment environment of the brushed DC motor were configured. The measured back EMF was applied to the model, and it was confirmed that the simulation results of the model were consistent with the measured noise and vibrations.
