Abstract

The heald shafts of a power loom are driven by electric D.C. or A.C. motors which have an external rotor or an armature connected to the respective heald shaft through two articulated couplings, for example snap locks, and a push-pull rod. The motors receive control signals from a computerized controller for reversing the motion direction of the external rotor or armature. The stators of the motors are rigidly mounted on a fixed axis secured to the loom frame.
