A test bench for students to rapidly test small concept motors. The idea would be that the test bench is configured for the students to rapidly test their motor design within a standardized manner. Student would then have a more comprehensive test results for their thesis.
This would simply be made up of a servo motor as drive/load machine and the test motor/generator is mounted onto test bench. The two TAPAS SDIs would then be used as the drives for both the servo motor and the test motor. See attached for example set-up.
Why use TAPAS?:
The intention would be that the test bench would be able to test many types of electrical machines over large fundamental frequency range, the TAPAS SDIs would allow for this capability without having to reconfigure drives. The GaN switches allow for very high switching frequency providing good quality sinusoidal waveforms to supply the test motors. This minimizes/eliminates parasitic converter effects on the test motors (torque ripple, iron loss, voltage distortion etc) providing better results to compare to simulations for the students to report in their final thesis. Coupling it with a Raspberry Pi would also allow for a low cost solution to be implemented for a full test bench, which could then be copied.
