EXPANDABLE ROTOR

An electric machine includes a stator and a rotor positioned in operational engagement with one another and defining a radial gap extending circumferentially between the stator and the rotor, the rotor including a plurality of rotor segments defining a plurality of segment gaps between adjacent pairs of the plurality of rotor segments, the rotor segments radially moveable relative to the stator, wherein movement of the plurality of rotor segments radially outward increases the radial gap between the stator and the rotor and the segment gaps between adjacent pairs of the plurality of rotor segments.
