Rotor and Method for Producing a Rotor

A rotor for a current-excited synchronous machine, comprising:

• a rotor main body, which comprises a plurality of rotor teeth distributed around a circumference, and rotor slots formed therebetween,
• wherein the rotor teeth are wound, along the rotor slots and on the front side, with conductor material in order to form a winding,
• wherein the conductor material is surrounded by a potting compound, thereby forming a potting body for mechanical stabilization,
• wherein the potting body has segments on front sides in extension of the rotor slots, and
• wherein, in at least one of the segments, a material cohesion of the potting compound is selectively weakened or eliminated at least in regions or portions.

A method for producing a rotor, comprising:

• providing a rotor main body, comprising:
• a plurality of rotor teeth distributed around the circumference;
• and
• rotor slots formed therebetween;
• winding the rotor teeth with conductor material in order to form a winding;
• applying potting compound onto the conductor material in order to form a potting body for the mechanical stabilization of the winding, wherein the potting body forms segments on the front side in the extension of the rotor slots;
• in at least one of the segments, selectively eliminating a material cohesion of the potting compound in some regions or in some portions.
