A dual fan module systemincludes a two-speed electric motorfor operating a first fan, a one-speed electric motorfor operating a second fan, and switching structure K, K, K, and Kconstructed and arranged to operate the system at more than two different speeds.

Multi-speed dual fan module system for engine cooling applications

A chokeis provided for suppressing radio-frequency interference of a brush-type motor. The choke includes a single wire having a portion wound about a coil axis A to define a plurality of coilsincluding two outermost coilsand. An attaching structureextends from one of the outermost coils and includes a loop structure. The loop structure is constructed and arranged to be inserted into a slotin a brush cardand moved into hooked relation with a retaining memberof the brush card that is associated with the slot so as secure the choke to the brush card. At least a portion of the attaching structure is constructed and arranged to be in electrical connection with a brushof a motor when the choke is secured to the brush card. An elongated end portionof the choke extends directly from the other of the outermost coils. The elongated end portion is constructed and arranged to be directly electrically connected to an electrical connectorwhen the choke is secured to the brush card.

Self-retained RFI suppression choke for electric motor

A method provides a heat shield on an electric motor. The motor has a housing and an endcap coupled to an end of the housing. The endcap includes a bearing pocket constructed and arranged to cover a bearing structure. The method includes coupling a heat shield directly to the motor so as to surround and cover the bearing pocket, with a portion of the heat shield being spaced from the bearing pocket.
