Abstract

228,928. British Thomson-Houston Co., Ltd., (Assignees of Hull, J. I.). Feb. 9, 1924, [Convention date]. Alternating-current commutator machines. - An alternating-current motor comprises a primary winding 1 and a commutator exciting winding 2 on the primary member, and a secondary winding 3 on the other member, connected to the commutator brushes 4, the core of the secondary member having also a squirrel-cage or other shortcircuited winding 12 loosely coupled with the winding 3. As shown, the windings 3, 12 are wound in different slots, and the radial pairs of slots are interconnected by air gaps for increasing the magnetic leakage between the windings at starting. An additional squirrel-cage winding of low resistance may be wound in a set of slots between those in which the windings 3, 12 are placed.
