Abstract: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 electr… Show more
