Abstract
In a converter motor, the converter electronics are integrated into the motor connecting box. The lower part of the motor connecting box is formed in one piece with a housing of the converter motor and at the front end than at the rear end. The edge of the upper part of the motor connecting box is shaped appropriately slantwise, so that the upper side is aligned to be straight. Connecting cables for power current and data communications issue from a stepped gradation in the upper part. The upper part has a plurality of openings for passing through cables which are oriented at an angle of less than 90° to one another and to the motor axis.
