Abstract
A rotor of a dynamoelectric machine is provided, the rotor comprising a shaft, an essentially cylindrical armature, an armature coil comprising aluminum coil wires and a drum commutator, which comprises an insulating support body and conductor segments which are attached to said support body and fixed therein by means of armature sections. Said conductor segments each comprise a copper running surface area and a connection area made of aluminum or a metal which can be soldered with aluminum (aluminum-compatible metal) having a soldering tag which greatly projects over the brush running surface. Said coil wires are soldered to the end side to the soldering tag of the respectively associated conductor segments and to be precise, without directly contacting the areas of the running surface.
