The invention relates to a driving unit for an electric tunnel thruster and to the support of such driving unit. Such driving unit is short/low and comprises an electric motor (8), a controller (7) and a support (6) for mounting the electric motor (8) and its controller (7) on a tunnel of the tunnel thruster. The metal support (6) is a radiator element both for the electric motor (8) and the controller (7). The axial length L of stator electrical steel stack (18) is less than 60% its diameter D. The electric motor (8) has a concave front flange (20) with a bearing socket, whereby a front bearing (14) of the shaft (16) is mounted in innermost part of the front flange (20) and is arranged fully or partially inside the front end-ring (15) of the rotor, creating in this way a cavity for the coupling to the reductor (11) of the propeller.
