Patent ID: 8866362

Claim:
An electrical machine stator, comprising: a stack of laminations configured to be assembled together so as to define at least one stator tooth, the stack of laminations comprising: a plurality of nesting laminations, each of the nesting laminations including a first edge section, a second edge section and a middle section extending circumferentially between the first and second edge sections, each of the nesting laminations further including a radially outer edge and a radially inner edge, at least one of the first edge section or the second edge section of each of the nesting laminations being configured to be engaged against at least one of the first edge section or the second edge section of an adjacent nesting lamination when the stack of laminations is assembled together; and a plurality of shim laminations, at least one shim lamination being disposed between each pair of adjacent nesting laminations, each of the shim laminations defining a substantially planar profile, wherein the middle section of each of the nesting laminations defines a substantially planar profile extending radially from the radially outer edge to the radially inner edge.
