Practice needs more than theory.

„The future will rely on original behaviour.“

The inverter is a key component in e- mobility. This is where the vehicle defines its DNA. Even electric motor driven actuator such as those currently used on steering servos, brake servos and in other chassis systems are equipped with control units. It is practically impossible to represent typical faults directly on the motor. Complex simulations or signal-level HiL systems are often necessary to achieve the most realistic environmental conditions possible despite only partial integration. Not with SPS e-motor emulation: This test topology permits the drive inverter and the control unit to be verified separately from the e-motor, without switching off the power stages and replacing them with complicated models. This brings huge advantages: No changes to the test object, no model development, no model validation, and no hidden costs. You can start right away! And the best thing is all this with real use-conditions that bring real results. And obstacles such as phase errors; errors in the rotor sensor, adjustment errors or motor tolerances are simply stimulated. The decisive advantage: The lower complexity, because only the electronic components themselves are tested. And the decoupling of mutual dependencies in the project plan.

Automotive, off-road, e-bike. The revolutionary test methods for technology leaders.

Many different functions and variables need to be tested. Fault scenarios. Safety aspect such functionality under the auspices of ISO 26262. Clear results are mandatory here. And the boundary conditions must correspond to reality. This is why manufacturers and suppliers rely on SPS. This drastically reduces the number of required tests. Costs can be cut and development cycles can be significantly shortened. In the automotive sector, in the production of off-road vehicles – and even of e-bikes.
