Abstract

A stator for an AC motor, includes windings of a first layer, which extend over a first region of the stator and are connectable to a first phase, and windings of a second layer, which extend over a second region of the stator and are connectable to a second phase, wherein the first region is offset relative to the second region and at least one overlap region is formed which is smaller than the individual regions, and wherein a temperature detection unit is arranged in the overlap region and is designed to measure the temperature of the windings in the overlap region.
