Electromotive adjustment drive for an injection unit
An electromotive adjustment drive includes an electric drive having a single motor with a rotor having a magnetic pole assembly, and a stator interacting with the rotor and having a magnetic pole assembly. The rotor is operatively connected to a member, such as a plasticizing screw of an injection unit, and is constructed for movement along a travel path, whereby one of the magnetic pole assemblies of the rotor and the stator is extended in relation to the other one of the magnetic pole assemblies of the rotor and the stator by a portion corresponding to the travel path. A spindle drive is positioned between the rotor and a motor housing and has a first transmitting element which is operatively connected to the rotor, and a second transmitting element which supports the first transmitting element. A plurality of switching elements is constructed for selective operation of the electric drive as a rotary drive or as injection drive.
