Abstract
706,170. Cooling dynamo-electric machines. HOOVER, Ltd. Dec. 19, 1952 [Jan. 2, 1952]. No. 32321/52. Class 35 A motor carries on its shaft 12 its own cooling fan comprising a 2-stage centrifugal fan having a fixed ring 40 secured to the end bell 2 and so arranged to divert the air flow outwardly from the blades 26 of the first stage fan disc 25 and redirecting it inwardly to the blades 35 of the second fan stage, the ring 40 being located entirely outside the periphery of the rotating parts. The cooling air is admitted through openings 21 after which the air flows partly via longitudinal holes 22 extending through the squirrel cage rotor 20 and partly between the frame central portion 3 and the outer perephery of the stator 7 through spaces between inwardly extending lugs 6 supporting the stator. The blades 26, 35 of the two discs have annular shroud bridges 27, 36 respectively near the edges of the blades.
