Paper Title:
Reduction Possibilities of Electrical Losses in Plastic Working Equipments
  Abstract

Plastic working technologies are frequently applied nowadays, as parts can be produced with larger productivity and smaller material loss compared to other technologies, at the same time the mechanical properties of parts are more favorable. Usually large tensile, pressure, bending or torsional forces, torques are required during plastic working. While pneumatic, hydraulic or electric energy is required to generate these. Used energy is determined by the losses of the energy required for working and that of energy conversion. The losses of working equipment are determined by mechanical losses and the losses of the energy converters applied, as well as by the manufacturing algorithm operating the working equipment. The advantage of electric driven working equipment over pneumatic and hydraulic driven ones is the better efficiency of energy converters, as well as the lower price of electric power. The disadvantage of electric converters is the large dimensions compared to hydraulic or pneumatic systems. Due to the development of electric servo drives the pneumatic and hydraulic drives are to be changed to electric drives in working equipment improving their control and accuracy features besides efficiency. In this paper the loss decreasing possibility of the working equipment with electric servo is investigated.
