Abstract
A method of fabricating a stator for an electric motor is provided. The method includes providing a plurality of stator laminations. Each stator lamination of the plurality of stator laminations is a copy of the same stator lamination pattern. The method further includes stacking the plurality of stator laminations in a sequence along an axis, comprising periodically varying rotational orientations of the stator laminations in the sequence. The method further includes joining the plurality of stator laminations as stacked in the sequence.
