摘要:
A submersible electric machine for transporting a liquid, the machine having a hydraulic unit with an impeller, and a drive unit with a housing defining a motor compartment having an electric motor inside. A drive shaft is connected to the electric motor, and extends from the electric motor to the hydraulic unit to a connection with the impeller. A top unit includes a housing defining an electronics chamber separated from the motor compartment by a dividing structural wall. The electronics chamber has a metal partition, having a natural frequency equal to or more than 500 Hz, connected to the top unit housing. A vibration sensor is directly or indirectly connected to the metal partition and monitors vibrations in at least two dimensions at frequencies ranging up to 500 Hz.
