Abstract:

The design and the working principles of a magnetoelectric actuator are presented. The designing principle is described, and the technical conditions required by an actuator are emphasised. A magnetoelectric actuator was designed and constructed on this basis, with the aim of driving the guide needle bar of a weaving loom equipped with rotating sinkers which form the shed and beat up the weft. The device described was tested under a loom’s working conditions, and we concluded that it fulfils the demands stated.
