Abstract

887,047. Core constructions. TELLERT, F. Nov. 18, 1958, No. 37058/58. Class 35. The slots in a square stator lamination for a dynamo-electric machine progressively decrease in cross-sectional area and depth from the corners to the centre of each side of the plate, and the tooth pitch and width progressively increase, so that the magnetic reluctance is substantially constant around the periphery of the plate. In the case of a singlephase motor the working phase windings occupy slots at the corners in staggered fashion with different numbers of conductors per slot. The auxiliary phase windings occupy the slots in the sides of the square plates. A number of laminations are secured together to form a stator core by means of clamps surrounding the corners or by welding together small tongues adjacent the corners. Specification 523,934 is referred to.
