Claim 9:
10. A stator comprising:
a plurality of split cores each having a yoke and a tooth, each one core of the plurality of split cores extending longitudinally along an axial direction, the plurality of split cores arranged circumferentially to be connected such that the yokes form an annular shape,
for each one core of the plurality of split cores, a coil is wound around the tooth;
for each one tooth of the plurality of split cores, the one tooth having a first axially extending sidewall and a second axially extending sidewall;
wherein for each one core among the plurality of split cores, a space occurs between the tooth of the one core and the tooth of an adjacent core; and
wherein in the space between the first axially extending sidewall of the tooth of the one core and the second axially extending sidewall of the tooth of the adjacent core are located in circumferential order: one of either a first portion of a first insulation sheet and a first portion of a second insulation sheet, windings of the one core, a second portion of the first insulation sheet, windings of the adjacent core, and another of either the first portion of the first insulation sheet and the first portion of the second insulation sheet, so that the windins of the one core and adjacent core are separated only by the second portion of the first insulation sheet and by an air gap, without any overlapping with the first insulation sheet.
