摘要： An electrical machine stator is disclosed that includes a stack of laminations configured to be assembled together so as to define at least one stator tooth. Each lamination may include an inner edge, an outer edge and first and second side edges extending at least partially between the inner and outer edges so as to define at least a portion of the at least one tooth. Additionally, each lamination may define a nesting feature between the first and second side edges, wherein the nesting feature of each lamination is engaged against the nesting feature of an adjacent lamination when the stack of laminations is assembled together.

摘要： The present disclosure relates to wind power generation systems having a segmented stator with a structural element and a plurality of coils. The wind power generation systems also include a rotor adapted to be rotated by wind to induce current in the plurality of coils and a lamination stack having a plurality of lamination plates disposed about the plurality of coils and a dovetail recess formed in the lamination stack. The wind power generation systems also include a dovetail bar adapted to be received by the dovetail recess and adjusted by a bolt to engage the lamination stack and the structural element of the segmented stator to form a torque transfer interface. Torque is adapted to be transferred from the lamination stack to the segmented stator via friction at the interface.

摘要： An electric machine and a stator assembly include a segmented stator having stator portions. Each stator portion includes end plates arranged axially on opposing sides of the stator portion, support plates arranged interior to the end plates, stator laminations arranged between the support plates, and stabilizing elements coupling the end plates and the support plates together. Each of the stabilizing elements has a dovetail portion coupled to the end plates and to the support plates. Connectors are provided to connect the stator portions of the segmented stator together.
