Abstract

Examples are disclosed that relate to an electric machine that achieves independent speed, variable frequency power generation and has increased power density, efficiency, reliability, and reduced complexity relative to conventional electric machines. In one example, an electric machine includes a stator, a first stationary winding coupled to the stator, a second stationary winding coupled to the stator, and a rotor. The second stationary winding includes a plurality of winding segments corresponding to a number of phases of power of the electric machine. The rotor extends through the stator and the second stationary winding. The rotor includes a plurality of rotor segments. Each rotor segment of the plurality of rotor segments includes a plurality of pole lobes that extend radially from the rotor segment. Two or more pole lobes of each rotor segment are located on opposing sides of a corresponding winding segment of the second stationary winding.
