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.

First claim

I claim:

1 . A system comprising:
a segmented stator assembly comprising a set of pole pieces:
arranged radially about a motor axis; and
each pair of adjacent pole pieces, in the segmented stator assembly, defining 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;
a set of windings, each winding in the set of windings arranged about a tapered annular interstice in the radial array of tapered annular interstices; and a rotor comprising a set of magnetic elements configured to magnetically couple to the set of windings to rotate the rotor about the motor axis.
