Netherlands Navy E-motor Pump (NLN-EMP) dataset. This dataset contains experimental vibration and motor current and voltage data of an electric motor pump set up, acquired at Fieldlab Techport as part of a research effort of the Royal Netherlands Navy. The experiments consist of measurements with a wide variety of faults, distributed over 2 set ups. One setup was operated at three different speeds, the other setup was operated at a single speed. The majority of faults were applied in multiple levels of severity.
