ABSTRACT:
An extruder drive has a housing, at least two extrusion worms each having a drive shaft extending into the housing, and at least one drive motor including at least one cylindrical stator fixed in the housing and a cylindrical rotor cooperating with the stator so as to be rotatably driven by the stator. The rotor surrounds the drive shafts, and each of the drive shafts is independently connected to the rotor for driving thereby.
