Abstract

239,560. British Thomson-Houston Co., Ltd., and Pollock, A. A. April 7, 1924. Windings; armatures, cooling. - Armature windings for commutator machines are arranged so that the current in one coil side is divided and returns through two parallel coil sides located two pole pitches apart. In one arrangement, Figs. 3 and 5, a four layer winding comprisescoil sides X, Y, Z with end windings 1, 2, the end portions 1 being straight extensions of the slot conductors. The current in conductors Y returns through conductors X, Z. In another arrangement, both slot conductors X, Z are offset by the full pole pitch, no straight end portions being provided, and the conductor Y may comprise a single bar of double cross-section. The series of axial channels formed between the top and bottom layers provides increased ventilation.
