Latest Patents
Nakatsuka's latest patents include two notable inventions related to armature windings of split stators. The first patent, titled "Armature winding of a split stator," describes an armature winding that features a slotted core divided by at least two circumferentially-spaced split lines. This design facilitates the disassembly and assembly of the split stator. The armature winding comprises armature coils in the slots of the stator core, which are connected to provide poles and arranged to allow for a plurality of armature coils divided at the split lines. Additionally, connecting and disconnecting means are provided to connect and disconnect the armature coils during the assembly and disassembly of the split stator.
The second patent, "Armature winding of a split stator for a rotary electric machine," further elaborates on the concept of a split stator. This invention also features a slotted core divided by split lines, allowing for easier assembly and disassembly. The armature coils cross the split line and are divided to have heads at both ends of the stator core. This design provides half coils wound through the back unit of the stator frame, ensuring that these coils are mounted on both sides of the split line.
