Abstract: An electric machine assembly includes a rotor formed from one or more magnetically conductive sheets having elongated magnetic flux barriers separated from each other in radial directions that radially extend away from an axis of rotation of the rotor. The magnetic flux barriers are separated from each other by magnetic flux carrier portions of the one or more magnetically conductive sheets. The assembly also includes a non-magnetic post coupled with the magnetic flux carrier portions of the one or more magnetically conductive sheets on opposite sides of at least one of the magnetic flux barriers. The non-magnetic post is elongated in the radial directions from a first magnetic flux carrier portion to a second magnetic flux carrier portion of the magnetic flux carrier portions on the opposite sides of the at least one magnetic flux barrier.
