Abstract :
DC motors are known sources of radio frequency electromagnetic noise produced by arcing at the motor brushes. A simplified model of electromagnetic radiation from a DC motor and associated wiring harness is introduced and compared to measurements. This model relates motor arc characteristics to the radio frequency emissions of the motor and wiring circuitry which can be used to guide engineers in the design process. This technique is intended to form the basis for a motor design aid
