Abstract
The paper focuses on the energy consumption of machine tool auxiliary drives. A detailed analysis of the electric power consumption of production lines in the automotive sector shows that machine tool auxiliary drives often have a low power factor. For uncontrolled induction machines this is an indicator for an operation in partial-load range and thus for an oversizing. The scope of this work is the evaluation of the energy efficiency of this auxiliary drives. Loss mechanisms of asynchronous machines are pointed out. The efficiency of asynchronous machines of different rated power will be assessed for a constant mechanical load. Beside the machine losses, ohmic losses of the lead wires are investigated to allow for a holistic assessment of the energy efficiency. The work shown in the paper was conducted within the project BEAT which is kindly financed by the Federal Ministry of Education and Research in Germany (BMBF).
