Abstract

147,818. British Thomson - Houston Co., (Assignees of Bergman, S. R.). Oct. 13, 1915, [Convention date]. Commutating poles and windings; cores; exciting.-The inner periphery of the field magnet 20 of a. continuous-current machine is slotted in two opposite quadrants and carries a series winding 21 with its magnetic axis at an angle of approximately 45 electrical degrees to that of the armature winding 22. Either wide slots 25, Fig. 2, or extra slots 30, Fig. 3, producing commutating teeth 26, are provided to improve the commutator. Auxiliary series commutating windings may be arranged in the slots 30. The slots 25, 30 may be closed by non-magnetic wedges 29, the remaining slots being closed by magnetic wedges 28. Specification 19210/09 is referred to.
