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： A wind turbine rotor blade assembly includes a rotor blade having a pressure side, a suction side, a leading edge, and a trailing edge extending in a generally span-wise direction between a tip and a root. An edge extension is attached along the trailing edge and includes a first strip member having a span-wise attachment section attached to pressure side, and a second strip member having a span-wise attachment section attached to the suction side. Each of the first and second strip members has an outboard edge and an extension section that projects chord-wise beyond the trailing edge. The extension sections are adhesively attached to each other outboard of the trailing edge along a span-wise length of the first and second strip members and define an adhesively bonded closure edge of the edge extension. A method is also provided for forming an edge extension on a wind turbine rotor blade.
