Abstract

The invention relates to a submersible electric machine (2) for transporting a liquid, the submersible electric machine (2) comprising a hydraulic unit that comprises an impeller (12) configured for propelling the liquid, a drive unit that comprises a drive unit housing (17) defining a motor compartment (18), an electric motor (19) arranged in the motor compartment (18) and drive shaft (20) connected to the electric motor (19), the drive shaft (20) extending from the electric motor (19) to the hydraulic unit and being connected to the impeller (12), a top unit that comprises a top unit housing (23) defining an electronics chamber (24), the electronics chamber (24) being separated from the motor compartment (18) by a dividing structural wall (25), and a vibration sensor. The submersible electric machine (3) is characterized in that the vibration sensor is directly or indirectly connected to a partition (30) arranged in the electronics chamber (24), is configured to monitor vibrations in at least two dimensions [2D] and is configured to monitor vibrations at frequencies ranging up to 500 Hz, and in that the partition (30) is made of metal, is connected to the top unit housing (23) and has a natural frequency equal to or more than 500 Hz. The invention also relates to a system comprising at least one submersible electric machine (2).
