The energy efficiency of servo drives is often assumed to be excellent. However, the energy consumption of those drives can often be significantly reduced. Among other methods, this paper introduces a new movement profile with a speed limitation and an energy efficient design of a cross cutting unit. The saving potential of all methods are shown by experimental results.
The conventional design of belt conveyor systems usually focuses on their mechanical parameters. In this paper, this design is reconsidered aiming at an improved energy efficiency. To this end, it is essential to consider the entire electromechanical system — from the belt to the electrical power supply. All these system components are modeled in order to estimate the losses at various operating points...
In this paper we present a guide to choose an energy efficient configuration of a pump drive system in an early stage of design process based on an user-defined load profile. All subsystem models are briefly presented, including different control methods (speed and throttle control) and single or cascaded pump drives. These models are based on free accessible parameters of data sheets. The analysis...
