Drive components for Test Stands

Test stands with efficient components from Siemens

Introduction

Technical objects are tested for the reproducibility of specific properties on a test stand. Test stands are available for many areas. Irrespective whether an automotive, roller, gearbox, motor, power or some other special test stand is involved.

In addition to the mechanical design for mounting the test object, the drive and control equipment as well as sensors must be provided to be able to produce the characteristics and record the measured values.


Test stands implemented with Siemens components meet the highest demands:

  • Speed and torque-consistency (low ripple)

  • Adaptable closed-loop system for maximum torque quality

  • SIEMENS closed-loop system for rotating-field frequencies above 1000 Hz

  • Energy recovery for braking without dangerous current harmonics

  • Energy exchange in the coupled DC link for multi-axis test stands

  • Integrated safety functions, e.g. SLS on entering the test cell

  • Integration of modern simulation tools, such as Matlab or Labview

  • Computer coupling for long-term data acquisition (CAN, PROFINET, PROFIBUS, Ethernet, EtherNet/IP)

  • High dynamic response, e.g. for the simulation of internal combustion engines
