Electro-pneumatic drive unit is realized in such a way that the central shaft (2) of the electric engine (3) formed by the stator (5) and the rotor (4) is connected with the shaft of the pneumatic engine (6) with an inbuilt turbine (7) by the serial constructional connection. Air channels of the two-zone air cooling are between the pneumatic engine (6) and the electric engine (3) arranged into circle. The pneumatic engine (6) has at least one opening for the intake of the pressure air. The two-zone air cooling consists of ribbing (9) of the first stator axial channels with the first output channel openings (13), which are alternately placed in the ribbing (9) with the second stator axial channels with the second output channel openings (15). The first stator axial channels with the first output channel openings (13) and the second stator axial channels with the second output channel openings (15) are covered by the sheath (10) of the stator (5).
