MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202617055856 A) filed by Arabelle Solutions France on May 01, 2026, for Fan Differential Pressure Cooling Structure For Dynamoelectric Machine.
Inventors include Ast, Jean-Charles; Morel, Eric; and Devillers, Philippe.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: A fan differential pressure cooling structure for a dynamoelectric machine (36) is disclosed. The cooling structure includes a fan (66) disposed on the outer surface of a rotatable shaft (14) on which a rotor body (12) having a field windings of coils (18) is mounted thereon. Movement of the fan creates a differential pressure that causes a flow of the coolant fluid circulating about the rotor body and the plurality of field windings of coils to be driven into the coolant inlet (64) and through various passages formed in the rotatable shaft to cool conducting elements (60) disposed therein and out through a coolant outlet (80) arranged on the outer surface of the rotatable shaft about the fan proximate a casing (38) within which the rotor and a portion of the shaft are disposed.
