An apparatus for electrically connecting at least four electrical conductors includes a connecting element and at least four shielding pipes, which are each provided for receiving at least one conductor. In order to enable a simple and economical connection, the connecting element forms pipe connection pieces and each connection piece is integrally joined or materially bonded to a respective shielding pipe.

Apparatus for electrically connecting at least four electrical conductors

A connection element for electrically conductive connections of at least four electric conductors. The connection element has a metallic electrode which has a cavity for merging the conductors and an opening into the cavity for each conductor. At least the outer surface of the electrode is surrounded with a paper insulation.

Connection of at least four electric conductors

A motor controller for controlling at least one electric motor has an operating signal generator for generating an operating control signal for the at least one electric motor and also a sound signal generator for generating a sound control signal. A mixer superimposes the sound control signal on the operating control signal in order to obtain a control signal for the at least one electric motor. It is then possible to dispense with loudspeakers and the like in the appliance which contains an electric motor with such a motor controller in order to output, for example, signal tones which indicate an operating state of the appliance to the user.
