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.
