Abstract: A system includes: a segmented stator assembly; a set of windings; and a rotor. The segmented stator assembly includes a set of pole pieces arranged radially about an axis. Each pole piece defines: a rim extending about a periphery of the pole piece; a recess arranged on a first side of the pole piece; and a shoulder arranged on a second side, opposite the first side, of the pole piece. Each pair of adjacent pole pieces, in the segmented stator assembly, defines a pair of linearly-offset and angularly-offset rims that cooperate to define a tapered annular interstice in a radial array of tapered annular interstices. Each winding is arranged about a tapered annular interstice in the radial array of tapered annular interstices. The rotor: encompasses the segmented stator assembly; and includes magnetic elements configured to magnetically couple to the set of windings to rotate the rotor about the axis.

Abstract: A system includes: a set of magnetic elements arranged radially about a motor axis; and a set of coil modules. The set of coil modules includes: a first subset of coil modules defining a first independent phase configuration; and a second subset of coil modules defining a second independent phase configuration, different from the first independent phase configuration. The controller is configured to: drive a first current at a first magnitude through the first subset of coil modules to induce magnetic coupling between the first subset of coil modules and the set of magnetic elements; and drive a second current at the first magnitude through the second subset of coil modules to induce magnitude coupling between the second subset of coil modules and the set of magnetic elements, and maintain a target power output.
