Development Test Bench for Electric Actuators

Our DC electric motor test benches are designed for the characterization of electric actuators during development and series production. The properties of electric actuators can be optimized and validated under environmental conditions.

  • Safeguarding over the service life
  • Characterization of electric actuators
  • Safeguarding operational stability
  • Quality assurance
  • Identification of characteristic values under climatic conditions

Development Test Bench for BLDC Drive Systems

Our BLDC electric motor test benches are used for development-accompanying tests and functional validation of drives for active vehicle dynamics systems. System functions can be optimized and validated under environmental influences, typically using standardized tests with synthetic setpoint profiles.

Key Modules of Our Electric Motor Test Benches

  • Drive technology

    The drive technology simulates the acting torques and speeds and thus significantly determines the performance and also the possible area of application of your DC electric motor test bench.

    The selection of suitable actuators, their dimensioning and the design of the control system are model-based for the test cases to be mapped, taking into account the properties of all relevant test specimens. In addition to your specific requirements for speed, control accuracy, dynamics, latency and synchronization behaviour, we naturally also take into account the investment and operating costs.

  • Mechanical structure

    When conceptualizing and designing the mechanical structure of your electric motor test bench, we attach great importance to

    • high rigidity,
    • a favorable inherent behavior of the structure,
    • low maintenance costs,
    • large set-up areas,
    • simple, fast and ergonomic set-up and consideration of the
    • and taking into account the conditions and constraints at the intended installation site.
  • Temperature control and media application

    Naturally, we offer you suitable and fully integrated solutions for the temperature control or air conditioning of your test specimen.

  • Restbus simulation

    Solutions from various manufacturers have become established for residual bus simulation and communication with the test object. We integrate your preferred hardware and software solutions into your steering test bench, ensuring that you can continue to use your established processes and toolchains. This allows you to utilize synergies and deploy your personnel flexibly.

  • On-board network simulation

    The on-board power supply simulation is used for the electrical power supply of the test object. In the simplest case, this module comprises a recuperating power supply unit, monitored power contactors for the automated switching of the terminals and measurement technology for recording the currents and voltages.

    There are also various expansion options. Examples include highly dynamic power supply units, an additional logic supply or the integration of SuperCaps for voltage stabilization for dynamic load cases. Other options include a connection option for external battery simulators or power supply units.

  • Measurement technology

    Measurement technology is another key component of an electric motor test stand. Depending on your requirements and wishes, our measurement technology team will develop various implementation options if necessary and discuss the advantages and disadvantages, existing conflicts of interest and expansion options with you. Here too, we are not tied to any particular manufacturer, so we can work with you to develop and implement the solution that best suits your requirements and boundary conditions.

  • Customized automation solutions

    We offer you customized software and hardware solutions for your electric motor test bench, tailored to your individual tasks and requirements. When designing suitable system and function architectures, we naturally take your existing automation solutions, processes and toolchains into account in addition to your standards, preferred lists and equipment regulations. If necessary, we implement individual interfaces, e.g. for the integration of additional peripheral devices, communication with higher-level automation systems or for the integration of the test environment into your database systems.
