Patent abstract
An EMI attenuation device includes a housing stator, a fan rotor, and an electrical bridge therebetween. The housing stator has an aperture therethrough, and at least a portion of the housing stator is electrically conductive. The fan rotor is adjacent to the aperture and has a rotational axis relative to the housing stator and a proximate surface proximate the housing stator. The fan rotor is electrically conductive, and the proximate surface is continuous around a rotational direction of the fan rotor. The electrical bridge is between the proximate surface of the fan rotor and a contact surface of the housing stator.
