Abstract

A stator for an electric machine includes slots for accommodating windings, the slots having a slot neck portion and a filling portion and extending radially between an inner circumference and an outer circumference of the stator, and including regular slots and misplaced slots. The slot neck portion of the misplaced slots has a dimension different from that of the regular slots. The plurality of slots and windings establish a plurality of phases, each phase occupying at least two adjacent slots, and the at least two adjacent slots include a regular slot and a misplaced slot resulting in reduced torque ripple and an associated reduction in vehicle NVH.
