Stator having adapted tooth geometry

A stator of an electric motor, having teeth distributed in the circumferential direction and extending in the radial direction and grooves respectively provided between the teeth, wherein respectively adjacent teeth each form a groove opening at the radial outer edge sections of said teeth, and the radial outer edge sections of the teeth each have a projection extending into the groove opening in the circumferential direction and each forming a free contact surface directed radially inward, wherein a contact surface width in the circumferential direction corresponds to a projection width (b) in the circumferential direction, and

• a ratio b/a of the projection width (b) in the circumferential direction to a groove opening width (a) in the circumferential direction is in a range of 0.1-0.15 and/or a ratio b/c of the projection width (b) in the circumferential direction to a projection thickness (c) in the radial direction is in a range of 0.5-1.0.
