Abstract: An arrangement for electrically conductively connecting a cup shaped copper contact part to an electrical conductor that is made of a plurality of individual wires containing aluminum. The arrangement has a cup-shaped contact part, which includes a bottom and a cylindrical sleeve integrally connected to and projecting away from the bottom with tight contact of the sleeve to the conductor. The cup-shaped contact part is configured to be pushed onto the conductor until the end face of the conductor rests against the bottom of the contact part. At least one rotating tool is configured to be removably placed with sustained pressure, subsequently to the cup-shaped contact part, until the material of the conductor is softened due to the increased temperature of the material of the conductor due to friction to such an extent that it integrally connects to the contact part.

Abstract: Method for manufacturing an electrically effective point of contact on the end of an electrical conductor with a plurality of stranded wires composed of aluminum or an aluminum alloy. At the end of the conductor arranged with the vertical course, initially a holder is placed surrounding the conductor so that the front side of the conductor is exposed and the point is accessible from the top. After the point of the conductor is in an axial direction, on the front surface a heat source of a temperature from 2000° C. and higher heats the surface. The material of the individual wires surrounding oxide layer are melted or steamed away until all the wires of the conductor including the same surrounding oxide layer form a one-piece combined aluminum composed contact part. After that the contact part together with the end of the conductor is cooled.

Abstract: A cast part includes a metallic functional region. The functional region extends in a first direction from a first side to a second side of the cast part. The cast part has a surrounding region at least partially surrounding the functional region. The functional region is shaped by a friction-based process. Further disclosed is a piece of equipment, such as an electrical machine which includes a further component and a device for securing the further component against twisting. The device has a connection between the functional region of the cast part and the further component.

Abstract: A method is provided for electrically conductively connecting a contact part on the basis of copper to an electrical conductor composed of a plurality of individual wires containing aluminum. A cup-shaped contact part which has a bottom and a cylindrical sleeve, which is integrally connected to the bottom and protrudes from the bottom, is pushed with tight contact of the sleeve against the conductor to such an extent until the end face of the conductor rests against the bottom of the contact part. Consequently, at least one rotating tool (6) is applied with sustained pressure, until due to increased temperature of the conductor, the conductor is softened to such an extent that it integrally connects with the contact part. The wall of the contact part is not broken through by the tool. Finally, the tool is removed from the contact part.
