  • Method and apparatus for fastening cooling fans to electro-mechanical machines
    Patent number: 8847446
    Abstract: A rotor arrangement for an electric machine comprises a rotor shaft and a rotor segment coupled to the rotor shaft. The rotor segment includes a main body and a collar integral with the main body. The collar includes an outer peripheral groove adjacent to the main body portion of the rotor segment. The rotor arrangement further includes a cooling fan that has a center opening defined by an inner perimeter. The center opening of the fan is configured to slidably engage the collar and is adjustable between an insertion diameter and a locking diameter. When the center opening is at the locking diameter, at least a portion of the inner perimeter of the fan extends into the outer peripheral groove in the collar such that the fan is retained on the rotor segment.
