Abstract: 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.

Abstract: A stator of an electric motor includes a tooth and a coil body. The tooth can be radially divided, from a central axis of the stator, into consecutive portions being a tooth root, a tooth neck and a tooth head. The tangential dimensions of the tooth root and tooth head project beyond those of the tooth neck. The coil body is U-shaped and, after attachment to the tooth, at least partially axially and radially covers the portions. The coil body can be force-lockingly secured to the tooth, between the tooth root and the tooth head, in a radial direction relative to the central axis. An electric motor having the stator is also provided.

Abstract: A stator of an electric motor includes a stator main body with radially oriented stator teeth, which carry coils of a multi-phase coil winding. A stator cap has at least one receiving contour into which at least one winding section of the stator winding is inserted. At least one contact connection has a deformable contact hook which receives the winding section in the course of a joining process and contacts the winding section captively following a deformation process. An electric motor having the stator is also provided.

Abstract: A stator system for an electric motor has multiple coil formers and stator windings that are wound on the coil formers. The stator windings are distributed over the circumference of the stator system and are arranged to form a substantially circular stator star. A number of the stator windings are electrically insulated in the axial direction in each case by way of a phase separator. The stator windings in each case of two coil formers are electrically connected as a coil pair in an electrically conductive manner by a conductor track. The conductor track is retained by a separating web that is arranged in the axial direction above the allocated phase separator and that extends in a radial direction.
