A method and electrical machine includes a housing and a tube within a channel, wherein a first coolant can flow around the tube and a second coolant can flow through the tube, whereby in order to cool the electrical machine, the first coolant is conducted in a coolant circuit within the electrical machine, the second coolant is conducted through the electrical machine, and the first coolant medium is conducted through a rotor of the electrical machine such that a compact and efficient cooling of the electrical machine becomes possible.

Electrical machine and method for cooling the electrical machine

A connection device for connecting at least two electric cables to an electric machine in a vehicle includes a housing and at least two contact elements. At least two openings, each allowing the passage of one of the cables, are located in the housing wall in such a way that only one of the cables that are fed in a direction through the openings in the housing and that continue to run in a straight line in the direction inside the housing makes direct contact with precisely one of the contact elements and can be electrically connected to this contact. All the other cables can be connected to a respective element of the remaining contact elements using a respective conductor bar.

A rotor of an electric machine includes a rotor lamination stack connected to a rotor shaft for conjoint rotation therewith. The rotor lamination stack extends from a first axial face of the rotor lamination stack to a second axial face when viewed in the direction of an axis of rotation of the rotor lamination stack. The rotor lamination stack has bores distributed around the axis of rotation and extending from the first axial face to the second axial face. A tie rod which protrudes from the axial faces when viewed in the direction of the axis of rotation is inserted into each bore. Fastening elements are attached to the tied rods at both axial faces so that the rotor laminations of the rotor lamination stack are pressed together. A fan is attached to the tie rods on the first axial face of the rotor lamination stack.

Telephone calls are handled via the Internet between an interworking unit relating to the calling subscriber and an interworking unit relating to the called subscriber. At least the telecommunications network to which the calling subscriber belongs as well as the interworking units are operated by the same provider. Access by a calling subscriber to the interworking unit and the passing on of the dialed telephone number of the called subscriber to the interworking unit are made dependent on the identification of the call as an Internet telephone call and dependent on the result of an access authorization check. Charging for use of the telephone network and of the Internet for such a call does not commence until the connection is made, as in the case of a call which uses only the telephone network.

Method for handling telephone calls via at least one telephone network using the internet

The invention enables a telephone subscriber to be advised via his telephone line of the arrival of a new e-mail. This is achieved by the e-mail server informing the point of presence (POP) of a subscriber to the Internet of the presence of mail, the POP passing this information to the local exchange of the subscriber, which in turn informs the subscriber of the presence of mail.
