Cylinder for rotation printing machine, moves axially and peripherally and has drive connection to electric motor with rotor and stator coil windings inclined to rotor axis in opposite directions

摘要

The cylinder (1) moves axially and peripherally and has a drive connection to an electric motor (7). The electric motor has a rotor (9) that is both rotatable and axially reciprocally movable and a stator (8). The rotor has at least two coils (11,12) that each interact with a stator coil (13,14). The windings (15) of the rotor and stator coils are inclined to the rotor axis in opposite directions.
