\ncame up with the idea to measure the Tau63 for the PT1 transmission behavior.

<\/a><\/p>\nThe software part is entirely written in G (LabVIEW<\/a>).

Via Back EMF (back electromotive force)<\/span><\/p>\n Back EMF is the voltage that pushes against the current which induces it. This voltage can be used to measure the motor speed.<\/p>\n Some Results for the electric current versus buoyancy measurements:<\/p>\nngg_shortcode_0_placeholder\n Some Results for the Tau63 measurements:<\/p>\nngg_shortcode_1_placeholder\n Last but not least, Ladies and Gentleman let me introduce you the Test-Stand itself \ud83d\ude42<\/p>\nngg_shortcode_2_placeholder\n","protected":false},"excerpt":{"rendered":" If you have ever worked in an academic environment you might know that there are students and then there are STUDENTS :-).
