  • Patent number: 8558421
    Abstract: A geared cooling device and method of manufacturing a geared cooling device. The cooling device includes a fan shaft, a fan coupled to the fan shaft and a speed adjuster coupled to a motor shaft of a motor and coupled to the fan shaft. The speed adjuster adjusts a rotational speed of the fan shaft to cause the fan shaft to rotate at a different rotational speed than the motor shaft to facilitate passing cooling air past the motor. The method of manufacturing includes coupling the speed adjuster to the motor shaft and to the fan shaft.
