Abstract
The present invention relates to systems and methods for a synchronous motor/generator including at least one back iron element which is rotated along with a rotor of the motor/generator. Rotation of the back iron(s) mitigates eddy current losses and improves efficiency in the motor/generator. The motor/generator also includes at least one stator winding supported in a non-conductive structure attached to the machine frame. The motor/generator of the present invention can also include at least one permanent magnet located in the rotor. The permanent magnet(s) cooperates with rotor windings to generate a DC magnetic field for the rotor. The components of the motor/generator can be configured in an axial gap topology, radial gap topology, or any other suitable topology.
