A plastics injection-moulding machine is to be equipped with a more compact drive that undergoes less wear. For this purpose, it is envisaged to integrate the direct rotational drive into the direct linear drive. Accordingly, the electric linear motor has a pot-shaped external rotor ( 13 ), in the inner space of which the main part of a hollow-cylindrical stator ( 16 ) of the linear motor is arranged and which is firmly connected to the output shaft ( 10 ). The rotary drive has a stator ( 18 ), which is mounted on the inner wall of the hollow-cylindrical stator ( 16 ) of the linear motor, and a rotor, which is firmly coupled to the output shaft ( 10 ) within the stator ( 18 ) of the rotary electric motor. This direct drive produces a very compact type of construction and it is possible to dispense with easily wearing threaded spindles.
