DEFINITION

Classification: 310/61

(under subclass 60) Subject matter having means in the rotor of the dynamoelectric device to provide a duct or channel to accommodate a fluid flow along the duct or channel.

(1) Note. Frequently, for example, a radial or circumferential inclination of this duct or channel is sufficient to induce flow of fluid therethrough without other means for maintaining the flow.
