Abstract

The invention concerns a motor connector for supplying voltage to a polyphase motor, with a connector housing that contains a number of electrically conductive pass-through elements whose number matches the number of electrical supply lines to be connected. By means of said pass-through elements, the supply lines can be connected electrically to contacts of a connecting plug mounted on the outside of a motor hosing of the polyphase motor, said contacts being connected to the winding conductors of the motor. The operating mode of the motor in delta or star connection can be selected by internal bridge configuration of the pass-through elements. For this purpose, the connector housing has a coding section that is separated from the connection section for the supply lines, with the coding section preferably designed as an enclosed coding chamber so that the connection section forms a connection chamber that is separated from the coding chamber. The bridge configuration is designed as an internal plug connection and is performed by means of a coding plug.
