Abstract
An electrical machine with a radial path air-cooled rotor is provided with prewhirl inlet guide vanes in the coolant inlet duct. The guide vanes are fixed members spaced from each other in an arc around the duct with their radial inward edges advanced in the direction of rotation of the rotor from the radial outer edges and preferably have a smoothly curved airfoil configuration so as to smooth and facilitate air flow through the end turn region and the slot channels.
