„One device. For almost all test objectives.“
Inverter tests are possible under full power in a laboratory environment. AVL SET offers e-motor emulators depending on the application and power class: From low voltage for the emulation of typical steering-servo motors, pumps or auxiliary motors; to high power emulators for the emulation of electric motors with over 1,000A phase current.

Simulated mechanics. Real electrical power.
Our emulator provides model-based emulation of an e-motor. The specific characteristics of the motor are set using parameters. The model is fed measured connection voltages and phase currents. The model then calculates the control values for the high performance phase amplifier. The electrical power flows exactly as for a real motor, safe, real. The mechanical world is simulated in real-time. Now tests on the drive inverter are possible with full power but without mechanical limitation. The EME does not influence the mechanics. Hence the mechanical behaviour can be exactly simulated in real-time while the e-motor is emulated on the phase connections of the drive inverter.
Testing of safety relevant functions (ISO26262) which are implemented in the inverter becomes more easy in such a setup.
