Claim 14:
15. The coil assembly according to claim 1, wherein at least one of:
the plurality of pole ring outer teeth each comprise a curvature or arch disposed about a curvature axis, wherein the curvature axes are each oriented at a right angle with respect to the longitudinal centre axis of the pole ring,
a plurality of pole ring inner teeth disposed on the pole ring each comprise a curvature or arch disposed about a curvature inner axis, wherein the curvature inner axes are each oriented at a right angle with respect to the longitudinal centre axis of the pole ring,
the plurality of counter-pole ring outer teeth each comprise a curvature or arch disposed about a counter-curvature axis, wherein the counter-curvature axes are each oriented at a right angle with respect to the counter-longitudinal centre axis of the counter-pole ring, and
a plurality of counter-pole ring inner teeth disposed on the counter-pole ring each comprise a curvature or arch disposed about a counter-curvature inner axis, wherein the counter-curvature axes are each oriented at a right angle with respect to the counter-longitudinal centre axis of the counter-pole ring.
