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.

A stator of an electric motor, the stator comprising:
- a central axis of the stator;
- a tooth configured to be radially divided, from said central axis, into successive portions being a tooth root, a tooth neck and a tooth head;
- said tooth root, said tooth neck and said tooth head having tangential dimensions, said tangential dimensions of said tooth root and said tooth head projecting beyond said tangential dimensions of said tooth neck;
- and
- a U-shaped coil body at least partially axially and radially covering said portions, after attachment to said tooth;
- said coil body configured to be force-lockingly fixed to said tooth, in a radial direction relative to said central axis, between said tooth root and said tooth head.
