Abstract
A core for an electrical machine includes a core body. The core body extends long a rotation axis and includes two or more core segments axially stacked with one another along the rotation axis. A plurality of the core segments define notches that are axially-aligned to one another and form an axial slot. The first core segment notch has an area that is greater than an area of a second core segment notch to accommodate thermal expansion of the core.
