Abstract
A system includes: a segmented rotor assembly; magnetic elements; and a stator. The segmented rotor 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 first recess arranged on a first side of the pole piece; and a second recess arranged on a second side, opposite the first side, of the pole piece. Each pair of adjacent pole pieces, in the segmented rotor 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 magnetic element is nested within a tapered annular interstice in the radial array of tapered annular interstices. The stator: encompasses the segmented rotor assembly; and includes windings configured to inductively couple to the magnetic elements to rotate the segmented rotor assembly about the axis.
