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.

An injection molding machine includes an actuating drive in form of an electromotive spindle drive and an energy storage device associated with the spindle drive. The energy storage device stores kinetic energy and can include two counteracting compression spring assemblies. The energy storage device is hereby loaded, as the spindle drive moves to a first end position, and unloaded, as the spindle drive moves in opposite direction to a second end position, wherein unloading of the energy storage device is accompanied by a power boost of the electric motor, and wherein the first force is equal to the second force at an equilibrium location distal from the end positions of the spindle drive.
