Abstract
An electric drive motor (4), in particular for a pump assembly, has a terminal box (8) arranged on the electric drive motor (4). The terminal box (8) includes a first section (10) arranged at an axial end (6) of the drive motor (4) and a second section (14) arranged radially to the first section (10). The second section (14) is radially spaced from the first section (10) and in the tangential direction has a width (b) which is larger than a diameter (d) of the first section in this direction. The second section (14) is connected to the first section (10) via a connection section (16) having two side walls which are away for one another. These two side walls extend from the second section (14) to the first section (10) and are angled to one another, such that they approach one another towards the first section (10).
