Abstract
An electrical machine with a radial path air-cooled rotor is provided with an axial duct inlet fairing. The inlet fairing, in conjunction with the other elements of the structure, reduces the inlet pressure drop by a substantial factor and provides more effective cooling. In addition, the fairing provides a simple means of orificing the rotor axial ducts for thermally balancing the rotor slot conductors.
