ABSTRACT:
A dynamoelectric device having a wound core provided with a plurality of circumferentially spaced, radially opening slots disposed in an annular array. Windings are provided in the slots and an annular slot closure formed of magnetic material having a plurality of through openings is disposed coaxially of the annular array of slots with the through openings being disposed centrally of the open end of the slots. The slot closure is formed of magnetic material and is defined by a stacked assembly of interlocked, coaxial annular laminations. The interlocking structure may include a pair of apposed fingers at opposite sides of the through opening. The fingers may be offset from the lamination to define a recess with the fingers of one lamination being disposed in interlocking fitted association with the recess of the adjacent lamination in the stacked core assembly. The openings and interlocking fingers may be stamped from the lamination.
