Abstract

1,022,842. Securing dynamo-electric machine coils. LICENTIAPATENT-VERWALTUNGS G.m.b.H. Feb. 19, 1963 [Feb. 20, 1962], No. 6686/63. Heading H2A. A dynamo-electric machine has a winding bar 1 held in a slot by a pair of wedges 4, 5 whose outer sides are parallel mutually and with the machine axis 8 and bear respectively against the winding bar and a slot wall, whilst sloping sides of the wedges opposite the outer sides mutually engage under the force of a biasing means which tends to cause a sliding movement between the wedges such as to increase the distance between their outer sides. The invention is shown applied to the rotor 2 in which the slot wall is the bottom of the slot, and the means comprise a compression spring 6; in another embodiment, Fig. 2, not shown, the pair of wedges is replaced by two mutually abutting pairs.
