imx METIS Hardware
imx METIS is based on a modular and expandable hardware concept. Two functional modules handle all key system tasks.
The Head Unit is responsible for measurement data acquisition and test sequence control. The Control Unit includes the required control electronics and motor controllers, among other components. A safety PLC complements the system. Power supplies and uninterruptible power supplies for the PC and communication components complete the core hardware configuration.
All components are integrated into a 19-inch cabinet, making every imx METIS solution a complete, ready-to-operate motor testing system.

imx METIS System Configuration
Configuration with Control Unit
Setting up imx METIS with a Head Unit and Control Unit for DC and BLDC/EC motor testing is straightforward. Pre-assembled cables connect the modules, while the required sensors are integrated directly into the system.
The setup is complemented by a suitable controllable DC power supply, which is also controlled by the Head Unit.
The motor under test is connected to the Control Unit. Voltage measurement is performed as close to the motor as possible to minimize measurement deviations and ensure high measurement accuracy.
Configuration with External Inverter
When testing induction motors or high-power synchronous motors, suitable external inverters are used. In this configuration, the required sensors are integrated into the test setup and connected directly to the Head Unit.
If the inverter system requires a DC-link voltage, either integrated or external power supplies can be used.
This flexible architecture allows imx METIS to cover a wide range of motor types, voltage levels, and power classes while maintaining a consistent approach to measurement, data acquisition, and parameter identification.
