Abstract

An electrical drive device includes a machine unit having a machine housing and power electronics having an electronics housing. At least one of the two housings having at least one protrusion for defined positioning of the machine unit and the power electronics against each other during and/or after assembly. The respective other housing having a complementary cut-out in shape and size for receiving the protrusion, wherein material forming the protrusion and the cut-out is electrically conductive at least in some sections. The protrusion and the cut-out are electrically connected to an earth for the purpose of earthing the power electronics or the machine unit.The electrical drive device and the drive assembly equipped therewith allow the electromagnetic compatibility to be optimized in a cost-effective manner.
