A stator of an electric motor has a number of radially directed stator teeth, onto each of which an insulating coil carrier for a coil of a multiphase rotating field winding is or can be placed. The stator teeth are connected to one another on the outer circumference on a yoke side, forming stator grooves. On the inner circumference, on a pole shoe side, a groove gap is respectively formed between adjacent stator teeth. Stiffening is provided on the inner circumference on the pole shoe side of the stator teeth, in the form of a stiffening element that projects into the or each groove gap.
