Abstract
1393025 Electric machine salient pole rotor coils UNELEC 18 May 1972 23530/72 Heading H2A In an electrical machine salient pole rotor, e.g. of an alternator, comprising a core which defines a plurality of polepieces about each of which a respective coil, e.g. 100, 200 is disposed, at least one elongate rigid member, e.g. 1, 2, 3, 4, which on one face is formed with a plurality of cooling fins (10 ... 13), Fig. 2, bears with another face against a respective one of two outer circumferential coil faces which extend axially of the rotor. The fins extend either longitudinally as shown, or transversely, of the member, and pairs of members are forced against adjacent coils by wedging devices 5 ... 7 each comprising, Fig. 3, a threaded rod (17) engaging two triangular wedges (15) and associated nuts (18). As well as cooling, the members also serve to hold the coils in position, and may be uninsulated or insulated from the coils by a varnish or, if they are of aluminium, by an oxide thereof. Their presence enable the coils to be impregnated with a silicone.
