ABSTRACT:
An insert comprising a lightweight structure configured for filling the gaps between axially spaced C-shaped lamination stacks and circumferentially spaced non-magnetic cradles on a permanent magnet rotor. The insert is secured to a rib by a dovetail tongue that fits within a dovetail groove provided along the length of each rib. The insert engages the adjacent cradles and has a circumferential surface that has the same radius of curvature as the top surface of the cradles.
