Title: Improvements in and relating to alternating current commutator motors
IPC: H02K27/10
Filed: 1928-12-17
Abstract: 302,909. British Thomson-Houston Co., Ltd., (Assignees of Bergman, S. R.). Dec. 22, 1927, [Convention date]. Alternating-current commutator motors; armatures, dampers on cores of.-In a motor having a squirrel-cage winding and a commutating winding separated by a flux path of a sufficient depth to carry the starting flux without excessive saturation and having sufficient reluctance for example by means of slits between the two sets of winding slots, to give substantially constant speed running conditions, the number of squirrel-cage slots is made less than that of the commutating winding slots, and the commutating winding is so arranged that all its circuits are equally inductive with regard to the squirrel-cage winding and with the eddy current bars in the slits when these bars are employed. By reducing the number of squirrel-cage slots it becomes possible to produce rotor laminae, especially of small diameters, which are mechanically stronger than those with equal slot numbers for the two windings. The invention is described in connection with a motor of the type shown in Specification 208,222. The stator, Fig. 1, has a single-phase distributed 4-pole winding 1 and the rotor has a repulsion winding 4 connected to the commutator. The squirrel-cage bars 10 are in slots which are joined by air slits 12 to alternate slots 5 of the commutating winding, these slits being wider than those used between the slots described in Specification 208,222. Non-magnetic eddy current conductors may be placed in the slits. To obtain equal inductive linking between all circuits of the winding 4 and the squirrel-cage and eddy current conductors, the coil pitch is made an uneven number of slots so that one side of each coil is over an eddv current and squirrel-cage bar while its other side is over unslotted iron.
