Your contracted testing – performed on our E-motor test benches

In the development of new drivetrain concepts and electric motors, as well as with quality assurance, it is crucial for a successful product to be quickly and efficiently tested with intelligent processing and logging of the measurement data and results.

imc offers a wide range of services related to the testing of electric motors: from on-site consulting and load testing, to the complete measurement of your electric motor. With our in-house E-motor test stands, we can test a variety of electric motors and components for you. For every type of test performed, you will receive all of the measurement data as well as a comprehensive test report with result data.

What types of testing does imc offer?

  • Characteristic curve recording/testing
  • Cogging torque, static and kinetic friction measurements
  • Thermal motor design based on nominal operating modes
  • Back EMF testing: the DUT is driven by the load machine and the voltage induced in the stator winding is measured. The DUT is brought to a predetermined speed in a defined time.
  • E-motor mass inertia simulation
  • Parameter-Identification testing of DC-motors
  • Parameter-Identification testing of EC-motors
  • EC-motor testing with integrated controller via CAN, CANopen, LIN and more
  • Determination of flux table for EC-motors
  • Automated test sequence following diverse test plans

What can we test for you?

  • EC-motors
  • DC-motors
  • 1- and 3-phase AC-motors
  • Capacitor motors
  • Components such as gearboxes, steering systems, etc.

The flexible, customizable solution:

The imc testing concept enables a customer-specific design of hardware components, thus optimally catering to each specific DUT. With this approach, for example, the customer could use their own controller or opt for using a standard one. Voltage, current, speed and torque ranges can also be specified as per customer request. The overall system can be expanded at any time. The heart of the test stand features an imc measurement device working together with the real-time processing of imc Online FAMOS. The imc solution allows for both the logging of all necessary measurement variables, as well as the entire control of all relevant system components.
