“…Thus, it is essential to accurately identify its high-frequency impedance characteristics. In general, high-frequency modeling uses a high-frequency equivalent circuit, and it is indeed powerful in the prediction of CE noise from PCBs [13][14][15][16]. However, in the case of RE noise, such a method is not such directive and could be less effective.…”

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.

“…Most models proposed in the literature are empirical, with parameters calculated using analytical approximations from measurements or fitting procedures [10][11][12][13][14][15][16]. These models are generally more accurate and quicker to develop but require experimental prototypes for calibration.…”

The trend towards electrification in mobility has led to the increased use of silicon carbide (SiC) semiconductors. These semiconductors are more efficient but also present challenges related to electromagnetic interference (EMI) due to their higher voltage derivatives. This paper introduces a new high-frequency impedance model for electrical machines. The proposed model distinguishes itself from existing approaches by being entirely derived from Finite Element Method (FEM) simulations, which include capacitances in the magnetic simulation. This approach achieves a balance between computational efficiency and high accuracy across the entire frequency spectrum, ranging from 100 Hz to 50 MHz. The model provides valuable insights during the design phase and was rigorously validated using data from 28 samples of an industrial machine.
