“…On printed circuit boards (PCBs), it was reported that the CE noise levels could be predicted by high-frequency circuit modeling of electronic components [5]. The RE noise level can be reduced in the design phase by signal integrity analysis, power integrity analysis, and trace layout of the PCBs [6][7][8]. However, they may not be suitable for predicting the RE noise trend or level of a three-dimensional (3D) electric motor unless its highfrequency modeling is present.…”

This paper presents a high-frequency model of a brushless DC motor to predict its radiated emission (RE) through high-frequency simulations of electromagnetic fields. The main RE noise path of the device-under-test (DUT) motor is specified as the stator winding, and its accurate high-frequency model in a full-wave EM simulator is proven by a two-port T-network. We analyze the induced surface current distribution according to the air ventilation hole shapes of the rotor housing and calculate the radiated electric field intensity using the high-frequency model of the DUT motor. The expected difference in the radiated electric field intensity by the hole configuration from the simulation model is verified experimentally.
