  • Method for the detection of errors in pump units
    Patent number: 8401806
    Abstract: A method is provided for detecting faults in a pump assembly having an electric motor, or faults in an electric motor, having at least one rotating shaft. A vibration signal is detected, the detected vibration signal is processed in a manner such that the influence of the current rotational speed of the shaft is eliminated, periodic signals are filtered out of the processed vibration signal, and the vibrational operating condition, in particular possible faults, is recognized by way of the periodic signals. Further, a pump assembly having an electric motor or an electric motor is provided in which this method is applied.

  • Submersible motor
    Patent number: 7821222
    Abstract: A submersible motor is provided for a submersible pump, the motor being configured as a single-phase asynchronous motor, which includes a main winding (6), an auxiliary winding (8), and a starting device (10, 14, 16, 18, 20, 22) for controlling the starting procedure of the submersible motor. The starting device (10, 14, 16, 20, 22) for the control of the current feed of the auxiliary winding (8) includes at least one electronic switch (20) in the circuit of the auxiliary winding (8).
