Abstract
A plastics injection-molding 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 (), in the inner space of which the main part of a hollow-cylindrical stator () of the linear motor is arranged and which is firmly connected to the output shaft (). The rotary drive has a stator (), which is mounted on the inner wall of the hollow-cylindrical stator () of the linear motor, and a rotor, which is firmly coupled to the output shaft () within the stator () 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.
