Abstract
1,217,855. Cooling dynamo-electric machines. ROTAX Ltd. 27 June, 1968 [14 July, 1967], No. 32556/67. Heading H2A. In a dynamo-electric machine comprising a rotor shaft provided with a bore, and a rotor structure having a plurality of circumferentially spaced polepieces, windings on the polepieces are retained in position by wedges located in the interpolar spaces and co-operating passages are provided in the shaft and rotor structure so as to communicate with the interpolar spaces such that coolant may flow from the shaft bore through the co-operating passages to the interpolar spaces and then over the rotor windings to discharge from the ends of the spaces. Coolant flows under pressure from a bore 20 in shaft 13 of an A.C. generator, through passages 21 to the interpolar spaces 16 (best depicted in Fig. 2, not shown), and then over rotor windings 18 and under wedges 19 to discharge from the ends of the spaces in the form of a mist, cooling the stator end windings 12 as it does so. Coolant sprays are also directed from apertures 33, 34 on to the end windings and the stator windings are further cooled by coolant obtained from annular passage 32. A pump 30 returns the coolant to the rotor bore and the passage 32 through a cooler 31.
