Abstract
An electrical rotating apparatus for controlling a harness cord associated with the shed of a weaving loom which includes an actuator including a rotor and a stator. The rotor is formed of at least two permanent magnets which are mounted within a tube so as to be spaced axially with respect to one another and wherein a plurality of stator elements are also provided offset axially relative to an axis of rotation of the rotor such that each of the plurality of rotors corresponds with a separate one of the plurality of stators. The polarities of one or the other of the permanent magnets or the stator elements are offset angularly relative to the axis of rotation.
