Abstract
A stator bobbin includes a first winding support with an inner radial portion, an outer radial portion, and a winding space defined radially between the inner radial portion and the outer radial portion with respect to an axis of rotation. The winding space is configured to receive a plurality of windings of the e-machine. The inner radial portion and the outer radial portion extend along the axis between a first end of the stator bobbin and a second end of the stator bobbin. The stator bobbin further includes a winding retainer disposed at the first end and configured for receiving and retaining an end of the plurality of windings. Also, the stator bobbin includes a contoured flow surface disposed proximate the second end. The contoured flow surface defines a nonlinear flow path for a fluid coolant of the e-machine.
