Easy to use, enables the user to set quickly the test parameters, and to produce clear and professional reports

Automated test reports in MS Excel and PDF formats

The principle of the test is to use a dynamic adjustable load with a servo motor that functions as a LOAD to the motor under test (MUT). In our test bench, the loading motor operates as a generator.

The system is very flexible for fast dynamic load changes (much more than the other brakes) – this is especially important for testing servo motors and for some BLDC motor applications. In servo motors, a fast response to torque changes is sometimes needed. We tune our RDS system accordingly, and we provide, in such cases, the ability to control the PID of the load control.

Such a fast response is also used in the automotive industry. With our “Road Load Simulation” test, we need to change very quickly from motoring mode to generating mode. During the “Road Load Simulation” test, the MUT runs in two modes: (1) when the MUT is working as Motor (to run the electric vehicle), and (2) when the MUT is working as Generator (to charge the vehicle battery).

The unit commission is user-friendly and no further adjustments are needed. Full digital control, yet no programming is required.
