Abstract

The invention relates to a stator in an electric motor, comprising ring segments (1) having radially extending support teeth (3) for receiving coils for carrying electric current and having radially external support segments (2) as supports for the support teeth. The support teeth have connecting elements (4, 5) by means of which adjacent ring segments are to be connected to each other.
