STATOR SEGMENT FOR A STATOR HAVING A SEGMENTED DESIGN OF AN ELECTRIC MOTOR, STATOR COMPOSED OF SIMILAR STATOR SEGMENTS AND METHOD FOR THE PRODUCTION OF A STATOR FROM STATOR SEGMENTS

摘要

The invention relates to a stator segment for a stator having a segmented design of an electric motor, to a stator composed of similar stator segments and to a method for producing a stator from stator segments, wherein the stator segment comprises a laminated core that has a plastic layer which is arranged between the winding region of the stator winding and the laminated core for electrically insulating the winding region from the laminated core. The plastic layer, in particular the plastic sheath, is configured as a groove section at the end region which is disposed in the circumferential direction thereof and as a corresponding spring section at the end region disposed against the circumferential direction, in particular so that the plastic layer of the stator segment can be connected to the plastic layer of a similar stator segment by means of a groove-spring connection, in particular in a form-fitting manner in at least the radial direction.
