Electric motor test bench

Electric motor test bench

The ongoing electrification of the drivetrain in cars and trains requires in-depth analyses of the drive, taking into account the respective boundary conditions and application scenarios.

The AVL electric machine test bench is available for testing test specimens and is able to simulate the electrical energy sources present in the system, the mechanical load and various peripheral requirements. The test bench environment enables the testing of electrical drive trains or individual electrical machines and can be flexibly adapted to customer requirements.
