Title: STATOR OF AN ELECTRICAL MACHINE, AND ELECTRICAL MACHINE COMPRISING SUCH A STATOR
Abstract:
The invention relates to a stator (100) of an electrical machine, comprising a plurality of stator teeth (110) arranged around a stator periphery which is adjacent to an air gap, every two adjacent stator teeth being separated by a stator slot (115); the stator slot comprising a slot base (150) and a side (140) of an adjacent stator tooth; said stator being characterised in that a connecting region between the side of the stator tooth and the slot base has an oval-shaped slot base-inner corner curve (161, 162, 163), said slot base-inner corner curve extending concavely from the slot base towards the side of the stator tooth.
