A dynamoelectric machine has a housing and a rotor assembly including a rotatable non-stepped shaft which projects through an opening in an end wall of the housing. A fan moves air through the machine to ventilate it and keep it cool. The fan is secured to an end of the shaft extending through the opening by a tab fitting in a groove formed in the shaft and a retention ring fitting over a hub portion of the fan in which the tab is formed.
