  • Split stator armature winding
    Patent number: 4604541
    Abstract: A split stator armature winding comprises a circumferentially split stator core having slots formed therein, a plurality of armature coils mounted in a single layer in the slots without bridging the splitting interface of the split stator, and a dummy coil of a closed circuit, the dummy coil being disposed so as to bridge the splitting interface of the split stator and to extend in the vicinity of the back portion of the coil ends of the armature coils close to the splitting interface of the split stator.
    Type: Grant

  • Armature winding of a split stator
    Patent number: 4594522
    Abstract: The present invention relates to an armature winding of a split stator having a slotted core divided by at least two circumferentially-spaced split lines to facilitate the disassembly and assembly of the split stator. The armature winding comprises armature coils in the slots of the stator core connected to provide poles and arranged to provide a plurality of armature coils divided at the split lines. Connecting and disconnecting means are provided to connect and disconnect the armature coils when the split stator is assembled and disassembled, respectively.

  • Armature winding of a split stator for a rotary electric machine
    Patent number: 4594523
    Abstract: This invention relates to an armature winding of a split stator for a rotary electric machine having a slotted core divided by at least two circumferentially-spaced split lines to facilitate the disassembly and assembly of the split stator. The armature coils crossing the split line of the split stator are divided to have heads at both ends of the stator core and provide half coils wound through the back unit of the stator frame such that these coils are mounted on both sides of the split line.
