Abstract

573,773. Cores for dynamo-electric machines. STEVENS, A. H. (Lear Avia, Inc.). Nov. 24, 1943, No. 19627. [Class 35] A motor stator consists of laminµ of the same size and shape having projecting portions so arranged that the projections of successive groups of laminµ extend alternately in different directions, and the width of the end rings corresponds with the edges of the projections so that the laminae and rings have a substantially uniform exterior. In the form shown, successive groups of laminµ 12 are reversed to provide fins 40 and the laminae are clamped between end rings 10, 11.
