ABSTRACT:
Two drive motors (251) drive the shaft of a load via a common drive wheel (19), either directly or via further gear wheels. The rotor shafts of the drive motors are constructed as two-pole single-phase synchronous motors having permanent-magnet rotors. The gear wheels mounted on the rotor shafts are oriented in such a way relative to the direction of magnetic polarization of the rotor magnets that when the arrangement is assembled and in mesh, the magnetic orientation of both rotors (27) relative to the main direction of the stator fields is the same for a positive stator current.
