<p>The present invention relates to an interconnection board (12) for joining the wire ends of a stator winding (7) of an electric motor, in particular of an external-rotor electric motor (1), having a connecting lead (13). It consists of a base part made of electrically insulating material, having reception opening for a front insulation shaft (11) of the stator (3) as well as, arranged in pocket-shaped recesses of the base part, plug connectors (18) for connection of the connecting lead, and a section (37) for accommodating a temperature controller and terminal lugs for connection of the winding wires of the motor windings. The pocket-shaped recesses are arranged in adjacent pairs which are separated from each other on the circumference of the reception opening such that each pair runs approximately tangentially to the reception opening and the point of tangential contact in each case lies, in a mirror-symmetry arrangement, on a straight line, through the mid-point of the reception opening, which is offset with respect to a mid-line Y-Y through the reception opening by an angle alpha of from approximately 30@ to 60@. The electrical connection of the connection elements which are formed as plug connectors is carried out using the terminal lugs via conducting tracks which are made in the form of stamped sheet parts and are connected with the base part, and the pocket-shaped recesses and the conducting tracks are arranged and dimensioned in such a way that the base part lies substantially within a circumcircle defined by the circumference of the stator (3). <IMAGE></p> |
