1. A stator of an electrical coolant drive, the stator comprising:
a stator assembly including an end face and a plurality of stator teeth having coils of a multi-phase stator winding;
a contact device having an outer periphery, said contact device disposed on said end face of said stator assembly for interconnecting said coils with phase connections; and
a deflection region disposed at said outer periphery of said contact device in a region of an inlet of the coolant drive, said deflection region deflecting a fluid flowing in through the inlet, and said deflection region being incorporated as a bead-shaped depression in said outer periphery of said contact device.
